Need help with VOB issue

Hi guys, I've got a DVD that was sent to me by another fellow preservationist. What I'm looking to do is edit the VOB files and then re-encode them using Sony Vegas.

Here is my issue:

The DVD doesn't appear to be encrypted in any way as I can simply copy the files over to my hard drive.

That said, here are the contents:

VTS_01_1
VTS_01_2
VTS_01_3
VTS_01_4
VTS_01_0
VTS_01_0.BUP
VTS_01_0.IFO

The total runtime is 47:35 long with a total of 10 chapters.

I've been able to open and edit VTS_01_2 through VTS_01_4 without a problem using Vegas. The problem comes when opening VTS_01_1 . The file is somewhere between 15:43-20:51 minutes long (didn't have time this morning to find out the exact length). But when I open the file in Vegas it only shows up as 00:15.14 seconds in length and the video is choppy as though the file is intact, but just not displaying correctly. It's only showing 15 seconds worth of video as though most of the video is hidden in that 15 seconds somewhere somehow. The file is 99megs. So there's no way the file should be displaying only 15 seconds.

Anyone have any ideas how to fix this issue? By the way, I'm using Microsoft Vista 32 Bit edition. and haven't had too much luck using DVD Decryptor to put it into a file or files that I can edit in Vegas. Either they show up in full and displayable in Media Player and they won't open in Vista or it loads in Vista and won't display anything more than 15 seconds.

Direct editing of individual VOBs is not a good idea. You're much better off demuxing the elementary video and audio streams - use PgcDemux or DVD Decrypter in IFO mode.

I've never used Vegas, so I don't know if it can work directly with M2V and AC3 files (maybe someone else can confirm this).

I did the demux in DVD Decryptor last night and couldn't get the files to import into Vegas. The M2V wouldn't import at all and I also tried raw but the raw file still showed up as 15 seconds. But the good news is when I got the M2V file I could see it as a whole in Media Player, but like I said Vegas wouldn't touch it. Any idea how to convert the M2V into an uncompressed AVI or something else usable in Vegas?

Thanks for your help too by the way. It's much appreciated.

The neatest way would be to use an AviSynth script with MPEG2Source(). Install AviSynth, and get the DGMPGDec plugin. Run DGIndex, open your M2V file, and save a D2V index file. Now in notepad, type the following:

LoadPlugin("pathname\DGDecode.dll")
MPEG2Source("filename.d2v")

Save with the extension .avs. Hopefully Vegas should be able to open this as if it were an AVI file.

Failing that, you could use VirtualDub-MPEG2 to load the M2V, and save out as an AVI. Use a lossless codec like huffyuv or Lagarith - but you will still need a fair amount of drive space.

I already have the huffyuv codec installed and that's been working like a charm with my capture program Winfast PVR (alas it's not working properly when I've tried capturing with Vegas for some reason). Anyway, That might be the simplist way since I have plenty of hard drive space. I've never used AviSynth but I might try that route if worst comes to worse. I'll post later on this evening with whatever results come out of this. Any other suggestions would be great if anyone has any.

The easiest way would be to load up the M2v file in VirtualdubMod and export it as an avi using the Lagaryth lossless codec. I've had a few problems with the huffyuv codec when using Vegas but Lagaryth works like a charm.

Also what format is original DVD? Is it Pal or NTSC? If it's Pal then just use VirtualdubMod but if it's NTSC then its best to use DVD2AVI and set the 2Field operation" in the Video menu to "forced film" to remove the 2:3 pulldown. This will give you a 23.976fps avi file. If your output video file has stuttery movement then the NTSC may probably have been encoded at 29fps without using the pulldown method. If this is the case just set it to "none". Also don't forget to change the "clip & resize settings" to > Filter type = precise bicubic, Video aspect = free & move the resize slider all the way up if using an anamorphic source.

The DVD should be NTSC, as I would imagine the source footage he obtained was as well (live club performance here in the US), but I never bothered to look. I can't see why he would have encoded to PAL considering this. He made the DVD for himself and made a copy for me. I've got a bunch of options so it would seem that having a few more can't hurt.

So, I tried the AviSynth route..and it wouldn't load into Vegas.

Then I tried the VirtualDub2-mpeg and that worked. I used huffyuv and the 7minute file ended up beign 12.5 gigs. Ah well, it's only temporarily anyway. Now I've got to figure out how to capture the audio. It has the same problem with only the 15 seconds going on. It's AC3 2 channel according to DVD Decrypt. Any ideas how I can get that ripped out as a 2 channel WAV? When I try to rip it from DVD Decryptor it saves it as a VOB. How do I extract it out of the VOB?

Thanks for the tips guys.

Looks like I found my own answer...

1. ran PGCDemux and created the ac3 file
2. ran PX3Convert to convert to a wav file.
