Merging VOB files

[Tydude4Christ]

Hello I'm new to the forums.
I was wondering what the best way might be to combine multiple VOB files. See, The Lord Of The Rings special extended editions of the films are on two separate discs and I wanted to make 1 VOB of both discs for encoding purposes for my PSP. I used DVDDecryptor to output both discs on two separate VOB's and now I'm lost. I tried to reauthor a DVD with both VOB's with DVDShrink and save it as an iso to be mounted in Daemon tools to use DVDDecryptor to decrypt the DVD to 1 VOB. The problem being that I have 2 Titles/VTS's. What might the best method be to do this. Thanks.

vobmerge , really you should search the forum or at least the "tools" part of the website before posting.

In my experience it is easier to load each vob in autogk and then use vdubmod to join them and compress to mp4.. what ever works for you tho

Visit the tools section of this site and look for vobmerge. It does a great job merging vobs.

Thanks for the help. Trying it right now. Sorry for such a newbie question but I looked at other threads and I didn't find anything. I actually don't want an mp4 for the PSP but a pmp, for full resolution video playback, using pmpmodavc a video playback app for the psp.

When i merged the vob's in vobmerge the audio was out of sync in virtualdubmod. Is there a way to get around this.

[drewzor]

that tends to happen when you pull vobs out.
There are a few ways of going about this and the easiest is using autoGk
or convert each before joinging them..

Or in virtualdubmod go to streams and stream list and right click audio track then under interleaving set an audio skew.. try 160 and then click play in virtualdubmod. keep trying until you get it back in sync..

Using VOBs without original ifo's is not 100% correct, in many cases VOB beginning from the second have internal audio delay. I'd recommend one of these ways:
1.TMPGEnc MPEG Editor for importing DVDs track by track (=title by title). Drag VIDEO_TS.IFO from the ripped folder to SET SOURCE window and follow the wizard. Both DVDs should have the same AR and audio type. It will make one big MPEG2 (program stream or video+audio elementary streams). Then you'll be able to re-encode it e.g. using VDubMod.
2.TMPGEncXPress imports DVDs the same way. Even if DVDs are encoded differently, you can output the result to a single track and select any codec on your system (not just internal MPEG encoder) for your target format.
3.(free tools) DGIndex=>Avisynth=>VDubMod (your codec + joining encodings from 2 DVDs)
