[mythtv-users] HD MPEG problems

[John Overchuk]

I'm having problems with my HD recordings from my comcast cable.  I am using 
an HD Homerun.  I am getting lots of artifacts accompanied by "chirping". 
The log spits out tons of these messages:

I could live with it, but it causes my frontend to crash every 5-10 minutes. 
Any ideas on why this is happening?  Is it just poor cable signal to my 
house?  I think I'm going to have a tough time convincing  my cable company 
that their line quality is messing up my Myth server.
