i keep running into similar problems no matter what i do, so there must be a flaw in my process somewhere... hopefully someone can point out what i'm doing wrong. here is a step-by-step on my latest project and the problem encountered...

if i am doing something wrong or am doing it inefficiently (as it takes a long time this way), please let me know how to fix it!

i am trying to put some of my VHS tapes on DVD. i want to fit about 8 hours to a DVD... so here's what i've been doing.

using Virtualdub, i capture video from my VCR in MPEG v2 (2400kbps) with PCM audio (48khz). i save the audio out as a WAV file.

i use TMPGenc with the VCD template to make a MPEG-1 file (changing the GOP to 18, which is what i was told to do to make it DVD compliant). i demux that file to a *.mv1 file and throw away the *.mp2 file. then i load the *.mv1 and the *.wav into Scenarist and try to make a VOB out of it.

the issue is i've done this with 4 two-hour segments, all in the exact same way. Scenarist accepts 2 of them... and rejects the other two as "video or audio buffer underflow." i was seeing this same problem before using MPEG-2 files that i had not captured myself... it would reject about half of them as "underflow."

what am i doing wrong? should i set the GOP lower? do i need to change something else in my process? HELP!

Thanks! :)

Hi,

I think GOP should be set to 15? For PAL anyway...
Although I don't know if this has anything to do with you're problem
