Similar problems here with the blank screen and mythfrontend at 100% CPU
but I wasn't getting a hung backend although the frontend reported:
2011-05-26 17:55:01.407 TV Error: StartRecorder() -- timed out waiting for
recorder to start
2011-05-26 17:55:01.407 TV Error: LiveTV not successfully started


I'm using Gentoo which uses snapshots of the 0-24-fixes git repository so
the version numbers may look a bit odd!!

mythtv-0.24_p20110430 was OK
mythtv-0.24_p20110515 has the error
mythtv-0.24_p20110524 is fixed!!

This latest version, also known as v0.24.1-1-g347cd24, seems to have
sorted it.

Cheers
