Hey, yeah. I'm using my Intel 980x PC so it has 12 threads (so 12 cores basically with the i7 technology). It seems that they are all over the place.. The Ut Video Lossless codec is multithreaded and recognizes that I have 12 threads so it uses them all.. So the speeds really tend to fluctuate a lot.

I have tried to manually make the codec use less cores like 2,4,6,8, etc and it makes no difference. I have also tried different codecs with no luck.

What do you think I should try? Its only a problem with 1080i and I'm not sure why.. And every video is the pretty much the same place at around ~4:30 the audio goes out of sync.. but its fine before that!

Also, I might note that I have my TV right next to my computer as well and can view both at the same time.. Using the audio from my TV, I can tell that the tv show is perfectly in sync during the capture.. I just don't know what throws the audio off..

I can also select the "resync video using resampling .." The default under Capture > Timings . and that fixes the audio in 1080i, but I don't have to do this in 720p?
