[MPlayer-users] problematic rtsp/pnm RealPlayer streams

[Marco Scoffier]

Hello all,

I have come across some RealPlayer streams I am can't read and was hoping
someone could tell me if I have a problem with my installation, or if
these streams are a problem. I can play other real videos just fine
using mplayer (though those usually end in .rm). 

Using the realplay application on this same linux box I can play
problematic files but the playback is really choppy, hence why I wanted to
-dumpstream to watch the files when they were all downloaded.

The streams are here:

  http://www.oid.ucla.edu/Webcast/ipam/

The error I get is:
