[mythtv-users] ComCast Digital

I have a backend with a PVR-250, PVR-350 and (recently added) a PCHDTV
HD-5500 plugged in to my SD "Basic Plus" Comcast Cable.

Where I live (Lancaster, PA) in order to get the basic broadcast
QAM-HD signals lined up with what I scanned I had to add the Over the
air broadcast channels as a seperate line-up in schedules direct.  And
then go back into the channel editor and delete all the music channels
(I wasn't gonna use them anyways).  That worked.  I couldn't get the
QAM-HD signals to match up with my regular line up in schedules
direct, since I really didn't have HD cable, I was just grabbing the
digital broadcast channels that they give for free without telling

I do use the NTSC side of the HD-5500 but only as my fourth priority
tuner, as compared to the 250 and the 350 the quality is marginal and
tasks the CPU.

Hope this helps.

God Bless,
