dvdshrink/dvd2one on MPEG1-based DVD

[txpharoah]

I've got a DVD9 that was based on 1856k MPEG1 files. There should be plenty of room to shrink it without a full re-encode. The actual files take up 4.5 GB, just about 125 megs too big.

However, DVDshrink shows no compression available and DVD2one crashes at about 75%

DVD2one DOES shrink the video up to the crash point. The files and the disc itself are fine. This has never happened before.

All of you DVD-copiers out there... that use shrinking software and not a full-blown re-encode... have any ideas?

The transcode of MPEG1 should function just as well as the MPEG2 transcode, alas, I usually work with only the highest-end MPEG2 when I transcode, so this is a bit out of my normal working expertise. So I'm stumped.

Does DVD Shrink's Reauthor mode work on this disk? You could go through and chop off the end of these mpgs if they contain credits. Then just replace the old vob with the new one and run ifoupdate. Other than that, sorry I'm a full re-encode man myself and I've never had the need to downsize an mpeg1 DVD.

This is a commercial piece, not a movie or anything like that. There are no credits. Just one huge max bitrate MPEG1 "movie".

Yeah, I know I could re-encode it from the start, but remaking the menu and all that would be included in that process is going to give me a headache. Some of the DVD copying process tends to get a bit technical for me, as there are some aspects of DVD I honestly do not understand at this time.

I'd need to have the original menus preserved and everything, and I have a hard time following along in AviSynth, IFOedit, and some of those other programs that are text-based or contain code. I wouldn't know where to start. I make things from scratch using programs, never a person for delving into reverse-engineering the stuff.

I can certainly understand not wanting to bother re-encoding and re-authoring, but just to let you know, when you re-encode/re-author a DVD you don't have to touch the menu's at all. All you do is re-encode the vobs that you want to downsample and then basically just replace the old vobs with the new ones. The menu's are always contained in a separate vob as the movie so they can just be left alone.

Do you want to have a try with TMPGEnc DVD Author??? It might help.

I have plenty of DVD's in which the MENUS are included in the .VOB's
PBS's NEW YORK a DOCUMENTARY is an example..

But it still seems the shrunken VOB's now with everything shrunk, should still function

The menu's are always contained in a separate vob as the movie so they can just be left alone.

or does this say "in a seperate VOB with the movie?
not from the movie as I read first"

The menu's are almost always in the same VTS set as the main movie. So if your movie vobs are VTS_01_1.VOB-VTS_01_5.VOB than the menu's will be VTS_01_0.VOB. There are of course exceptions, but 99% of all commercial DVDs are produced like this. As long as the menu and the movie are not physically in the same vob then you can just leave the menu vob alone and simply re-encode anything else that is too large to fit on the disk and all menu's and commands will be left unchanged.

Just from what DVD's I have authored with my own content, placing the menu's in the same vob as the movie would present lots of problems, so I doubt there are many DVDs authored like this.

The only additional thing I have ever seen stored along with the main movie was a trailer.

Sonic MyDVD and DVDit! are known to put all files in the same VOBs. Several others too, but these are ones I'm most familiar with.

This disc is the same. The menus and the short segments (all run together and accessable by chapters) that make up the full "movie" of this commercial work are on the same VOB set. The menus, the introductory speech and the beginning of the piece are all on the first VOB.

Herein is where the problem lies and why anything other than a transcode copying process is going to take lots time and Advil for this not-so-old but not-so-young non-tech guy.

So any help on finding a copying program that works would be the best method and the most appreciated.
