[olpc-help] Opera & Mp3

[N1ST]

Anybody have Opera installed and able to play mp3s?  First issues I have is that Opera seems to freeze the XO when downloading the MP3.  If/when it completes, it downloads the file but it doesn't play.  I have Helix installed (was the necessary?), but I don't know how to config Opera to associate Helix with MP3 files.

Any help would be appreciated.  My end goal is to play winamp, or Real, or Win media streams, but baby steps for now.
