Some episodes rip, others don't

[winifreid]

I am trying to reencode a DVD with 3 TV episodes. My method was to Smartrip/demux each episode to a ac3 and m2v file. I then converted the acs to wav and loaded them into VS7 to encode to mpeg2. I will then author them all to one DVD with VS7. But the method doesn't work with the 3rd episode. I can not open the m2v file with either VS7 (hangs) or TmpGencplus (format error). I can play the original vob in PowerDVD and open the m2v file in Vdubmpeg. I can also open the wav file. As I said I could open the first 2 episodes and encode them. I tried shrinking the vobs and then demuxing to m2v, but it made no difference. Any ideas? Any solutions. The only one I can think is to convert to .avi in vdub and then encode in VS7. But that would take a lot longer. Thanks

What is VS7 ?

Sorry, I have more questions...

Is the 3rd episode on the same disc as the previous two?
If yes, are they in one continuosly VTS file or each has its own VTS ID's?

And, ( Sorry what I'm going to ask may seem irrelevent, but maybe I have a better method)
Why are you de-muxing them and re-encoding them?
Are you trying to reduce the episode file sizes so you can add more to a discs?
Was transcoding wouldn't fit your needs?

(one more)
What is Vdubmpeg?

Use Headac3he to convert ac3 directly to mp2. Try ripping as vob and then demultiplex with TMPEG.

Ulead Video Studio 7
Not sure about vts, but it looks like they are all with seperate ifo. They were all on the same disk. They are rather large files and transcoding in shrink required about 55% compression, so I thought I would try re-encoding. I don't have a problem with ac3 file, only the m2v. I might try the tmpgenc demux, but I don't see how the first 2 episodes could demux with Smartripper and the last one will not.
Thanks

Sorry I don't use Ulead Video Studio...

My advice/opinion would be shrinking them with DVDShrink, by removing the unneccesary stuffs like DTS audio track or extra language track will probably get you to 65% plus...

Re-encoding the files I don't think it'll improve much on the quality wise.(Compare to the 55% compression )
But you can try frameserve that problem file thru VDub and feed it into TMPGEncPlus. It worked for me when I have a problem file which TMPGEnc wouldn't accept.

Ulead Studio is not the problem. I tried to demux with TmpGencPlus and it could do the first vob, but not the next 2. It could do the othe vobs from the other episodes. So there is a problem with the last 2 vobs. It is odd since they play fine. I want to re-encode because even with reauthoring just the 3 episodes in Shirnk, I get 55% compression. At this point I am just curious why the vobs came out the way they did.

TMPEG requires there be only one vob file for it to demultiplex. You could set DVD Decrypter to rip as one large file or VOBEDIT will demultiplex from a set of vob files.
