The same with AC 3/2...about 150 MB. Most quality "shrink" programs will allow the user to remove DTS, AC 3/2, and subtitles. Unfortunately, Intervideo's DVDCopy 3 does not remove these unchecked items from the final output file. The result? Much higher compression with the main video title than its competitors CloneDVD, Recode, and Shrink.
The purpose of a transcoder is to remove data from the video title that it believe to be non-visible to the naked eye. Note that the audio tracks remain undisturbed. Since DVDCopy 3 does not strip DTS and AC 3/2 from the final compilation, its transcoder must remove an ADDITIONAL 700 to 800 MB of data from the video title (average 2 hr movie) to fit to a DVD-5 disc. Bottomline, why remove an ADDITIONAL 20% of data from the video title when it is not necessary???
If we include the DTS and AC 3/2 audio titles with the other shrink programs, then DVDCopy 3 MAY come out on top. However, only NOOBS would want to transfer EVERYTHING from a DVD-9 to a DVD-5. This will ALWAYS result in a longer transcoding time and a lower quality picture.
As end users, we always want to believe that there exist a product that could outperform all other competitors. Since audio/video can be very subjective, we rely on the "experts" to recommend a "superior" product. In the case of DVDCopy 3, the numbers don't add-up. How can a product provide better video quality when it must remove 20% more data from the main video title? Could it be that DVDCopy spends more $ in advertising? Cough, cough....
With the movie only selection you only keep the sound track for that section. If you notice, DVDCopy3 does have the sound track broken down to the different chapters. So, one only keeps the sound in the language of choice and the sound for unwanted chapters is deleted. Seems you didn't pay close attention to the options. Go back and try it again and then compare the completed product with the encoder of your choice.

Wander over to AfterDawn and take some lessons. Other than the foreign language tracks, there are many times I want to record the entire disc. I have the software to do it. As I said, up to about 7.5GB content total, DVDCopy3 does an excellent job. When the compression starts getting near 60% I use Rebuilder with Cinema Craft Encoder (RB/CCE). I've done movies with that encoder setup and the copy is indistinguishable from the original (viewed on a 60 inch screen and up to 300% magnification).
I'm not talking about playing with numbers. Get in there and do the actual test and view the finished product. Here are the programs I currently have:
VSO DivX to DVD
DVD Lab Pro
Quick inventory and I may have left out some things like the WinDVD6 player and other codecs and utilities. The point is, I have a library of software to choose from and know how to use it. My main "go to" choices for quality DVD backup are DVDCopy3 and the RB/CCE programs.
The proof is in the end product. Furballi, the answer to your question
How can a product provide better video quality when it must remove 20% more data from the main video title?
is simple, A Better Encoder. Part of the question was erroneous though. You keep adding those 20% figures and 700MB tracks and it just isn't true. Granted it doesn't trim down the finished product like DVDReMake or Lab Pro, but then how many do? If I needed to, I have the editing tools to do the task, and I don't find them necessary. I wonder if you've actually done many recordings with DVDCopy3. If you had, you would have seen the quality.
furballi... I pointed out that one should use a PC with the recommended requirements to do an honest evaluation. You said you had a P3 with 600MHz (barely meeting minimum requirements). Plus what OS are you using on your P3? XP would have it dragging and 98 doesn't meet the requirements of DVDCopy3. You were complaining about program file sizes and updates I find curious. DirectX9 is just an update, not something to complain about (normal windows update item). I have a lot of programs larger than DVDCopy3 which is about 48MB. Instant CD/DVD suite is about 510MB. Which leads me to wonder about the capacity of the machine you're trying to record DVD with. The media my look the same, but it takes a lot more to record DVD than CD. DVD Shrink is one of the programs that caters to older operating systems. So for older systems, Shrink is probably the way to go. Most of the newer programs are written with the NTFS file system in mind, not the old FAT32.
In the end, I'm not advertising for anyone. If they'd pay me I might. Shrink is good and I'm not putting it down. I just prefer DVDCopy3 for it's speed and video quality. I don't want anyone to take my word for it. Believe your own eyes. Go to http://www.intervideo.com and download the trial and give it a good work out. It doesn't cost anything to try and they let you use the full function Platinum for the trial. Just give it an honest evaluation and pay attention to the recommended system requirements. Minimum requirements can lead to minimum usability and minimal results in some cases.
