yes, I looked at the source for ffmpeg, couldn't see anything that really stood out. But without documentation its not a fun program to debug.
Makes me glad I have both macs and pcs.
Really I mostly use my powerbook for everything, even when I need to do something in visual studio, I just connect to the desktop pc in my spare room via wi-fi using microsoft remote client for macs.
For java development I perfer the mac, and I'm really starting to like xcode.
Not sure how much time I want to spend on trying to make h264 work on windows, its just that the h.264 encoding I did with 42dvdvxplus on the mac look better than the mp4 with nerorecode on windows, But the xp machines are faster.
