PM> I found that it said
PM>
PM> # Complete MPEG-4 compliance.
PM> # H.264/MPEG-4 AVC codec.
PM>
PM> I thought it was meaningful to add
PM>
PM> # Complete MPEG-4 compliance (except for MPEG-4 part 2 the Windows
PM> version does not support PAR (Pixel Aspect Ratio) essential for high
PM> quality video at low bitrate. Some OS-X versions are rumoured to
PM> support PAR, but the claim is still to be proven).
no codec (video and audio) claims?
PM>
PM> # H.264/MPEG-4 AVC codec (as for PAR for MPEG-4 part 2, the Windows
PM> version has no support for SAR (Source Aspect Ratio) essential for
PM> high quality video at low bitrate. Some OS-X versions are rumoured to
PM> support SAR, but the claim is still to be proven).
I think it should mention that the Apple's own codec is only up to Main
Profile and Progressive Mode only
PM>
PM> Please drop a comment if something changes dramatically.
PM>
PM> Kind regards

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