[mythtv-users] Mythtv freezes with Hd Homerun

[Don Brett]

I just bought a new HdHomerun (HDHR3-US), installed in a test box with 
upgraded MythDora, updated firmware to the latest (20120128), followed 
instructions here:

It scans OK (finds all the local stations), then when I try LiveTv it 
tunes the first channel perfectly.  The next channel freezes x-windows 
with either a completely black screen or puts up the station info on a 
black screen (channel number, show name, resolution, etc.).  The only 
way out seems to be a reboot.

I've tried it a bunch of times with different default channels...some 
work, some don't.  Sometimes a channel that failed earlier works on a 
later try.  What did I miss?
