[mythtv-users] channel tuning

[Cotter, Paul M.]

That's interesting - I also have Comcast and I also see 5 in B/W and 6
is garbage.  Almost everything else is fine, though I think the tuning
is slightly off on most of the channels.  Is Comcast's channel table a
little different or something?  I couldn't find anything using a Google
search.

I have a similar problem (Comcast in MA,USA) with a PVR250MCE using the
tuner on analog cable. When I use us-cable, ch 5 is poor and black and
white, ch 6 is full of junk, but everything else looks very good. With
the us-cable-hrc setting, 5 looks great, 6 is as good as the cable box
picture (which is poor), and the rest look fuzzy & wavy. Ch 5 looks
great on the cable box.

I am use Knoppix 3.4 on the HD with latest mythtv apt package 0.15-1,
ivtv 1.9 with card type patch. The tuner type set to 2.

I tried adding 12dB of attenuation to the input, and it didn't help so
it's not overload. I also turned off the TV and cable box in case it was
interference, but also no help.

Is this a bad card?
