I took another crack at this, and it turns out they are actually both in
sync, just not on the PS3. I recently found out that my laptop was
indeed not getting proper airflow, resulting a throttled CPU, but I can
play back these videos fine now that I have fixed the problem. It plays
in sync perfectly with a software player (Media Player Classic, using
CoreAVC to decode). However, using the PS3, it is slightly out of sync -
over PS3 Media Server, the difference is quite noticeable, and played
from the PS3's HDD, it is still noticeable, but only barely. I think the
problem is with keyint. I set it to 300 since I typically deal with NTSC
content and I didn't want the default 250, but since this is a PAL
capture, am I correct in thinking that the higher keyint value will
throw off hardware players? Oddly enough though, I have done 24p Blu-ray
titles with the same settings and those are in sync.
