Comment 6 for bug 660833

I seem to be having this same problem. I performed a fresh install of 10.10 and MythTV has been working fine. I just got a HD HomeRun and added it to the system. After that going to Watch Live TV would crash Myth Frontend and log me out of my session as described above.

I simply removed the HD HomeRun from my setup since I was out of time for the evening and things went back to working. I'll try switching playback profiles tomorrow.
