You're almost right ;-)
Windows ONLY:
When NOT using QT, RR can play UNCOMPRESSED AIFF and WAV and
(compressed) AU with
"play ac xxx"...(using some very low system routines, if i remember
right...)
When using QT every format supported by QT can be played inside a
player on Mac and Win.
Can some *nix please give me some info about usable audio/video format
on Linux/Unix?
Thanks in advance...
Is there a QT for *nix?
(Is there a life before death? ;-)

See above...

If diskspace or download-time does matter, then QT offers some superb
compression types
like MP4 or MOV/AIF with Q-Design etc...
Drop a line (offlist) if you need more info about (correct) formats ;-)

Its fairly easy to create an installer with RR :-)
I already created one and if i find the time i may post it on my
website...

Exactly!
Storing media outside the stack WILL make updates easier...
Since the player/image can store the reference to the media, you can
simply replace
media, as long as they have the original size, format and name...

Sorry, no way to have WMV or WMA files in RR :-(
(Its a MS private-brand ;-)
QT cannot handle them (yet?) and without QT you can only play AU, AIF,
WAV, MP3, MPG
and AVI (even DivX, if the right compressor is in the system!) in a
playerobject(!)...
WindowsMediaPlayer >= 6.4 has to be installed!

Yo, amen, brother ;-)
One can easily check "the qtversion" and act accordingly...

Since there is a jungle of formats out there, it is understandable that
the dox cannot
cover ALL the aspects...
