# Complete MPEG-4 compliance (except for MPEG-4 part 2 the Windows
version does not support PAR (Pixel Aspect Ratio) essential for high
quality video at low bitrate. Some OS-X versions are rumoured to support
PAR, but the claim is still to be proven).
# H.264/MPEG-4 AVC codec (as for PAR for MPEG-4 part 2, the Windows
version has no support for SAR (Source Aspect Ratio) essential for high
quality video at low bitrate. Some OS-X versions are rumoured to support
SAR, but the claim is still to be proven).
Please drop a comment if something changes dramatically.
Kind regards

BTW. He he, Complete MPEG-4 compliance is a mighty big claim. Complete
is sort of absolute. A bit like eternity is a mighty long time,
especilly towards the end.
