a player that has played everything i throw on my N900 so far is VLC Player (does the same on the PC, playing everything. Like, if you put a Salami in your CD Drive, it will play *something*)

But it always uses full CPU Speed on my N900, even when just playing back MP3s it goes to 950 Mhz.

What about WebM, does the N900 support it in the Mediaplayer? Think it should.
