Finally got it to compile and.... the file produced has completely corrupted
However, if I replex it using:
ffmpeg -i IN.AVI -acodec copy -vcodec copy OUT.avi
it seems to clear it up and the AVI works perfectly on my DVD player (aside
from aspect ratio issues but that's another story!)
I finally got a decent nuvexport, well I say decent the bit rate is WAAAY
out and of course it forces a recode...
