What codecs does it support? .wav? .wma? .ram? .mov? doesit play streaming media also? Just questiocns cuz I could not find it on the site or the wiki.

Most likely yes for all of them, it depends on your sound engine really.

what madpenguin8 means is that the only thing that limits the media that amarok can play is the currently selected engine.

for example, realplayer will be able to play .ram files, i know xine supports wma, etc.

but, for the files to be in your collection (not just browsable through the file browser) TagLib 1.4 needs to be able to read them. this is currently limited to ogg/flac/mp3/others i am forgetting. but no wma/wmv/m4a support from taglib.

which really should be changed
