Ain't technology grand??
It seems like only yesterday that I wrote my
article about ripping DVDs
to CD-ROM. Since that time, two things have happened: the price of
DVD burners have come down to under $75 and software has progressed to
the point where you only need a couple of easy-to-use programs to copy a
DVD disc. I know that my DVD ripping guide was pretty complicated
for the casual user - it certainly doesn't pass the "mom test".
But just look at the history of MP3: way back in olden days (1997) you
typically needed 4 or 5 different programs to make MP3s - one to rip the
audio CD, another to encode the MP3, another to add ID3 tags, etc.
Of course, nowadays most folks use just one "all-in-one" program to copy
those CDs. The good news for you is that while we're not quite
at the "all-in-one" stage yet with DVDs, we're close. So go ahead and read this
article, then read the DVD ripping article and tell me which one's
easier. Go ahead... I'll wait. You back? OK, good! |

To copy a DVD movie
you will need the following:
|
| |
| A modern version of
Windows - at least Windows 98 but 2000 or XP would be better. |
| A DVD burner |
| 1 or 2 blank DVD discs
|
| Two free programs:
DVDDecrypter
and DVDShrink |
| Software that supports
burning DVD video disks (I use
Nero) |
|
Around 12-14GB of free disk
space (temporarily) |
| |
| |
|
Summary: |
| |
|
We will use
DVDDecrypter to copy the DVD's files to your hard drive. We will
then use DVDShrink to remove extraneous parts of the disc and re-encode
the video. Lastly, we will burn a copy of the re-mastered movie to
a blank DVD disc using standard burning software.
|
| |
|
Why? |
| |
|
Most DVD movies you buy in the stores are "dual layer"
discs. This means that the DVD has two layers on which to
store data, unlike CDs which only have one data layer. At this
point in time, most DVD burners can only burn "single layer"
discs. This means that a
DVD disc you buy at the store can have up to 9GB worth of data, while
the most data can can fit into a "home brew" DVD is 4.7GB. Because
of this, you can't simply do a "Disc Copy" like you can with audio CDs
or most CD-ROM discs. You will either have to burn 2 discs using paid-for software like
DVDXCopy
*or* remove any superfluous data and re-master the DVD (this is the path
we'll take). Additionally, every Hollywood DVD is protected with
CSS (encryption) and Macrovision (copy protection) both of which must be
removed before a backup can take place. |

|
Assumptions |
| |
|
This "how-to" article assumes that you are trying to
copy a "single format" DVD movie. This is a DVD with either the
full-screen or widescreen version of the movie, but not both.
Copying DVDs of TV shows (or other "short form" features) and DVDs
that contain both full-screen and widescreen formats is a bit
trickier and will be covered in a "part 2" of this article at a later
date. Also, this article is assuming that you're making backup
copies of your own DVDs for archival purposes. |
| |
|
Please respect the copyright laws of your jurisdiction and DO NOT make
backup copies of any discs that you do not legally own! |
| |
|
Step By
Step: |
| |
1) Download
DVDDecrypter
and DVDShrink.
DVDDecrypter has an actual installation routine; DVDShrink only requires
you to unzip the downloaded file and run the DVDSHRINK.EXE file when the
time comes. Also, if you haven't done so already, free up 12-14GB
worth of space on one of your hard drives. |
| |
2) Insert the DVD movie in your DVD drive, then
start DVDDecrypter. You
will see a screen that looks like this: |
| |
|

| |
3)
DVDDecrypter will, by default, select the hard drive with the most
available disk space. You can change the output location to a
different disk if you'd like by clicking on the folder icon in the
"destination" section. If you're happy with the destination
location go ahead and click on the "DVD to Hard Drive" icon at the
bottom of the screen. |
| |
4) Copying the DVD to your hard drive will take
around 20-30 minutes depending on the speed of your computer and the
length of the film. Once
it's done you will get a confirmation message. When you get this
message, close DVDDecrypter and
open DVDShrink by double-clicking on the DVDSHRINK.EXE file. Once
DVDShrink is open, click on the "Open Files" button and point to the .IFO
file in the folder DVDDecrypter created in step 3. You will then see the following
screen: |
| |
|

Here's some explanation of the
screen above: the left-hand column shows the contents of the DVD: the
menus, the movie and any extras that appear on the disc. In the
right-hand column you have (from top to bottom): the video re-encode
ratio (more on this in a minute), the audio portion of the movie, the
subtitles and a preview window (the black space at the bottom).
|
| |
You will notice
in the picture that the video re-encode ratio is currently at 45%. This means
that the movie will be compressed at 45% of its original quality in order to fit all of
the discs' contents onto one DVD-R (remember how genuine DVDs can hold
twice as much data as DVD-R discs?). You can certainly go ahead
right now and make copy of the disc, but at a 45% compression ratio, the
picture won't look very good. You could uncheck the boxes for any
foreign subtitles and soundtracks - this will certainly save space and
decrease the compression ratio to maybe 50% or 55%. But the
picture still won't be as good as it could be. In fact, if you are
trying to copy a movie with a lot of action scenes, you will probably
need as much space for the movie as possible. This means getting
rid of the menus and extras. If
the compression ratio says "100%" - which might happen if you're trying
to copy a short film or one without extras and/or foreign language
soundtracks, you're ready to burn. Skip ahead to step 11! |
| |
5) Click on File > Deep Analysis. This will
examine the movie in greater detail and will provide better quality
video. Completing the "Deep Analysis" will take around 20 minutes or
so, depending on the length of the movie and the speed of your computer.
It might also change the compression ratio a few percentage points in
either direction. Come back in little while then continue with step 6. |
| |
6) You now have a choice to make.
If you want to preserve the movie in its entirety - with the cute
animated menus and all the extras - uncheck any foreign language audio
tracks and subtitles and be sure to keep EITHER the Dolby Digital
OR the Dolby Surround OR the DTS soundtrack (if the disc
has DTS as a sound option, some don't) then skip ahead to step 9.
If you'd like to make the movie look better by getting rid of the
extras, continue to step 7. |
| |
| 7) Click on the + sign next to the "Main Movie"
entry in the left hand column. You will see something like this:
|
| |
|
 |
| |
8) Click the "re-author" button near the top of the
window. A new DVDShrink window will open up. Drag the main
movie - which will be something like "Title 16" - to the new DVDShrink
screen. The screen will now look something like this: |
| |
|

(Click to enlarge) |
| |
Notice that without the extras the compression ratio
is now down to 78%. This is much better. If you uncheck all of
the soundtracks except the Dolby Digital (AC3) one and all of the
subtitles except for English subtitles the compression ratio goes down to
99%. This is means that the video quality will be essentially unchanged from the original. You
may prefer to use DTS over Dolby Digital, but since that soundtrack is
bigger, the compression ratio goes up to 93% - not bad, but not as good
as Dolby Digital either. As a rule, I prefer DTS over Dolby but
since I still don't have my rear speakers set up, I really don't care
either way - picture quality is paramount in my mind. Because of
this, I'll stick with Dolby Digital: |

9) Click the "Backup!" button. You will be
presented with the following screen. Select an output directory
and check the region-free box if you wish (I always do!). If you
skipped the "Deep Analysis" in step 5, check the box to do so now.
If you've already done this step, the box will be ghosted out: |

10) DVDShrink will do its thing. It will take
around 10 minutes if you've already done the Deep Analysis or 30 minutes
if you elect to do the Deep Analysis at this stage. Once it's
done, you will have a folder full of .IFO, .BUP and .VOB files - much like the
files you copied to disk with DVDDecrypter in steps 1-4. All we need to do now
is burn the files to DVD! |
| |
11) Open Nero (or whatever burning software you
use). Select New > DVD video. Nero will create a new DVD
layout. Simply drag all of the files you created in step 9 to the
red VIDEO_TS folder on the new blank disc: |

12) Insert a blank DVD and click the "Burn" button!
You're done!!! Don't forget to delete the original and re-authored VOB folders after testing the new DVD disc! |
| |
| |
That's all you have to do to copy a DVD! Note
that if you re-authored the movie (that is, you did steps 7 & 8 above)
you will not see any menus or FBI warnings or anything when you put the
DVD in your player - the movie will simply start playing! You'll
probably need to play around with this some to get things working just
the way you want to. When I first authored this article, I was
terrified to have any compression ratio of less than 90% on a copy.
Since then I've dealt with movies that have been shrunk down to 65% or
even 45% with very little loss in quality. For example, The
Last Samurai will shrink to around 58% of the original even if you
re-author the disc and remove all extras and foreign language
soundtracks. I suppose this is due to the length of the film.
However, the difference in video quality is hardly noticeable to me! |
