[mythtv-users] Signal Issues and HDPVR

[Joe Henley]

Matthew,

I run MythTV v 0.25.2, with Time Warner cable, and with the same 
pixelization problems.  I found I could improve things a bit by changing 
some settings:
CPU usage:  from High,reset down to "Medium"
Ringbuffer: Increase from 18,800 kB to 28,200 kB

But their impact is small.  The key is to get the TWC techs out to 
address the problem.  I've had them out ALOT!  They've added line amps, 
replaced cable connectors, replaced the cable splitter, etc., etc.  When 
the problems are at their worst, the cause is usually some issue back at 
the "head-end" -- ie., TWC facilities.  If you take a hard stand and 
insist on good service, you'll see alot of failed attempts, alot of tech 
visits to your place, but eventually they can work thru and fix things 
(...until the next time).

My take on it all is that the HD-PVR is very sensitive to problems and 
TWC has a lot of problems.  It can, and will work, but it's not easy nor 
quick.

Good luck!
