Reinstalling Mac OS X codecs?

[John A]

My iMac G5 has had this problem already for a little while, and I think it's in need of codecs reinstall. iTunes and QuickTime work normally, but that's about it. RealPlayer and Windows Media Player 9 play video, but without sound. Same goes for their respective browser plugins. I think it happened when I installed Myst V Demo, or when I was playing around with Flip4Mac. I know where the codecs are stored on a Windows machine, but how do I access them/reinstall them? Thanks for any help.

Well, all the codecs are installed in either /Library/Quicktime, or ~/Library/Quicktime.

OK, thanks for that. I'll let you know how it goes.

flip for mac. codecs are in library/quicktime or home/lib/QT. and without
flip4mac you have no wma.

I tried deleting the contents of my /library/quictime and ~/library/qt (after I had made a backup, of course), and tried reinstalling Flip4Mac. No change though.

Do you have the DivX codec installed?

Strangely, have you tried starting up GarageBand? Supposedly this fixed lost sound issues in RealPlayer (at least).

is it possible that your flip4mac timed out?

YOU ARE A GENIUS!!!! Starting up GarageBand and then closing it restored everything!

I'm totally amazed. :) :) :)

Glad that worked.. what a weird work around for an (still) unknown problem.
