[mythtv-users] Debugging Pixelation w/ Ceton InfintiTV 6 PCIe

[Kevin Calvert]

Hello,

Any suggestions on figuring out what's causing pixelation on my ceton
infinititv card? It's very intermittent but is universal--it effects all
channels.

I've had a comcast tech out a couple times and, of course, the pixelation
has never happened when they were here but all my signal levels looks just
fine to them. I just called again while this pixelation issue was just
happening and they said all signals going into the house look excellent.
While it was happening the internal ceton webpage shows, what appear to be,
ideal SNR and signal levels (37.4dB / -3.5dBmV).

I have 1 backend and only two frontends, but this problem occurs on both
frontends when it happens, so that leads me to believe there actually isn't
any physical cat6 (frontends are wired via cat6) or hdmi (nvidia card in
frontend to tv) connection issue here.

One strange thing that I notice in the ceton log page are frequent
"pcrlock" messages when nothing is actually changing on my end (one tunner
is being used and the channel isn't changing)....

Doesn't look right to me but I'm about as beginner as you can get when it
comes to cable signal stuff. Is this something that indicates anything?

Any other recommendations to point me other directions are appreciated.
