yes, it's supposed to be mp4a for audio and mp4v for video

could this be a MPEG system stream ? (even if they aren't supposed to be
versionned ?)
i must say i'm lost between all the different MPEG stream types that exists
(program, transport, elementary, video, audio, ...)

mplayer says that about this file :

Playing TeeSummerTranceMix2004.mp4.

==========================================================================
Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding)
FAAD: compressed input bitrate missing, assuming 128kbit/s!
AUDIO: 44100 Hz, 2 ch, 16 bit (0x10), ratio: 16000->176400 (128,0 kbit)
Selected audio codec: [faad] afm:faad (FAAD AAC (MPEG2/MPEG4 Audio) decoder)

as a side note, i am unable to play any of the MOV files i have, and it looks
like qtdemux has a lot a problems reading zlib compressed headers (not the case
for this particular bug, for which headers aren't compressed at all)
