"player" objects rely on QuickTime or Windwos Media!!!

Yes, exactly!

You need at least ONE multimedia architecture on the target pc when 
using
"player" objects!

Controller are a QuickTime ONLY feature!
We are not using QuickTIme just for fun ;-)

I won't sign this ;-, but WindowsMediaPlayer version  >= 6.5 should be 
the least requirement
to play MP3...

Only uncompressed AIF (and WAV files, but that does not look to be 
correct) and
(compressed) AU files can be played by "play ac xyz" without 
QuickTime/WindowsMedia...

QUOTE:
"(Player) ...that uses QT, which although much slower and more memory 
intensive can play
many more formats than the default play command which uses low-level 
sound routines
in Win32 and MacOS which don't support compression.

Hope that helps...

This is just a rule of thumb and will not prevent you to TEST, TEST, 
TEST, TEST, TEST and TEST...

Since we're talking about WINDOWS, it will NOT "play for sure" ;-)
