DVD-Lab Pro erased my video files!!!

[Gaskan]

I re-encoded a Pal SVCD to NTSC and dropped the converted video and audio assets into DVD-lab. I received several error messages about the the mp2 file not being audio and the mpv's audio was invalid. Eventually the last time I tried it said the files were not valid because they were in use by another program. I searched in Task Manager to see if MPC was stuck open, but it was not. when I went to explorer to find the files they were still there, but the files sizes were now 0kb. Anyone ever heard of such wackyness w/ this program. I would hate to stop using because it is very useful, but I don't want to keep wasting hours of work. Any help of where you think I might have screwed up would be helpful. Thanks.

I doubt it's dvdlab that screwed up. When was the last time you checked for trojans and virii?
Are you positive the encoder actually produced a valid ntsc mpeg, and not a 0 byte file? What re-encoding process did you use? Is the source material still in good shape? Have you checked it for errors? What's MPC? Did you have WMP open at the same time, or some other viewer/player?

Sorry to be vague, I did:

Re-encoded the source to NTSC SVCD specs it produced a 3 GIG MPG file
I encoded video only.
I converted the audio w/ Besweet GUI from Pal 25 FPS to NTSC 23.97 FPS mpa to mp2.
resulting audio file was 160MB
I tried loading the assets together. It wanted to demultiplex the video (eventhough it was just video, so I renamed it mpv (possible catastrophic error?)
I still have the source video Pal 480x576, audio seems screwy so I will work on that seperately. Thanks for the quick response.

Demux the video in tmpgenc, or strip audio to .wav in virtualdubmod.
Re-encode video, no audio, in tmpgenc.
Use Goldwave to re-encode audio.
Author in DVDLab.
Check for sync in a good player such as WinDVD or PowerDVD, not WMP.
If necessary, adjust audio in Goldwave, or use DVDLab's audio delay function to fix.
Reauthor, check again...
