Hi folks. I'm having a problem with DVDMF4. Here's the situation. I took an mpeg2 VOB file (from a 3:2 pulldown DVD), and demultiplexed it with VobEdit to get an AC3 audio stream and a M2V video stream. I then decoded the AC3 stream with BeLight, made some changes to the wav files (without changing their time length), and reencoded the AC3 stream. Then I re-multiplexed the new AC3 stream with the original M2V stream, using Imago mpeg muxer.
The resulting mpeg2 file plays perfectly in VLC. Audio and video are synched perfectly, and both audio and video play back smoothly. I wanted to burn this file to a DVD, so I inserted it into a new DVDMF project. When I hit the "Next" button in DVDMF, I get to the "DVD player simulator" screen which shows the DVD remote on the side. If I try to play the simulated DVD, the video stutters. The audio plays fine, and in fact the audio is still in sync with the video (as far as I can tell), but the video keeps pausing and skipping.
Does anyone know why this happens, and how I can solve it?
TIA!
Mpeg2 plays fine in VLC, but stutters in Movie Factory 4
I know the feeling... Ulead's programs seem to be rather picky about the MPEG format... 
I've been working on a troublesome VOB, and I was able to convert it to an MPEG acceptable to Video Studio and DVD Workshop by using a program called SUPER (free!). Perhaps it will work for your VOB.
The bad thing is that it seems to re-code the MPEG, and then Ulead wants to re-code it again!
I used SUPER's highest bitrate and the re-coding didn't degrade the video noticeably... although I hate doing that!
You'll will need to use some other tools for de-multiplexing, remultiplexing, etc...
Other users have noted problems with Ulead "rejecting" AC3 files generated with unlicensed AC3 encoders. I don't know if SUPER was using a supplied (unlicensed) AC3 encoder, or if it was able to "tap-into" my licensed Ulead codec... But, the AC3 that it generated had dropouts... So, I let Ulead (DVD Workshop) encode the AC3 (and multiplex it) from a wave file. (I think Movie Factory can do this too.)
----------------------
None of the de-multiplexing / re-multiplexing programs I tried would make an MPG or M2V file that Ulead "liked". There are several "VOB to MPEG" programs, but either they produced an MPEG unusable by Ulead, or they produced a low-bitrate SVCD file. I also tried several "MPEG repair" programs... They didn't work for this VOB either...
