Yes I should have said I see no problem with a ubuntu frontend, for
example, running VDPAU using the same version (but from the mythbuntu
repos) so I think this is pi or openmax related (ie openmax just doesn't
understand the video aspect of the radio stream so it falls back to
something the Rpi's CPU can't cope with).

If it's seektable related I guess it could be hard for someone else to
reproduce.  If I can help let me know how!

This sort of thing is another possibility I'll investigate if there's no
easy fix for the Rpi; using some sort of transcoding to remove the
video/extract the audio.
