I'd like to know if there are different types of AVI file.
I have many of them and I see that some of them could be played with
xine or real play or whatelse, some of them have very poor quality and
the rest are impossible to play, for example Avidemux can only open
half of them whereas xine can play others....it seems that each file
it's different from anyone else.
I'm really confused, are there different types of compression or what?
Thanks,

Stefano

Yes, there are different types of AVI.

The AVI format is really a blanket format - you choose the way you
encode the video and audio under it.

For example, you can have a DIVX avi, am indeo avi, a microsoft codec
avi (worst codec ever, from like 1992) and so on. You don't even have to
compress it - don't EVER do that ( huge file, amazingly jerky playback.
As far as I know, this form is pretty much a bitmap sequence with
optional sound)

The audio can also be encoded in different ways (mp3, ulaw, truespeech,
ETC...)

I feel your pain. If you need to, try getting mplayer also. It helps
having more than one player, so long as you can keep mozilla from
auto-opening one with the same player every time

For example, I have Xine and MPlayer for videos. Sometimes mplayer works,
sometimes not, etc.

Yeah

Both Video(could be MS MPEG4,DivX X.X, XviD, 3ivX an so on and so on...)
and Audio(MS PCM, MP3... you know... a lot)

MPlayer rulez forever i have ALL possible audio & video codecs in it
(downloaded from mplayer's site) so i can play under Linux video files
which couldn't be played under Windoze with inet connection to M$ site for
update!!!
