Realplayer, xmms shoutcast on Debian 3

I've gotten RealPlayer working fine on another distro and even BSD, but for some reason although audio files work video files are silent. My audio hardware is apparantly a combination of intel i810 and AC'97, so I've enabled the relevant modules.

A second, perhaps related, problem. xmms plays fine an mp3 on disk but quickly appears and disappears when I try to open a shoutcast stream with it using mozilla. I use the settings for netscape described in the manual, and these settings worked on other distributions(tm).
