I'm using an HVR 2250 to watch ClearQAM channels from Comcast. I am in
one of the areas where they're passing out the Pace DC50x DTA's.
Last night, when I tuned to some channels, all I'd get is a big
information box in the center of the screen that said "You should have
gotten a lock by now". So, basically I lost the channels.
I rescanned for them with scte65scan, populated the database, and now
I've got the channels back. I looked at the SQL file scte65scan
generated and it looks like Comcast has changed the frequencies it's
broadcasting some stations on.
So, now I can tune to the channels. But, the video is jerky. I am
getting prebuffering pauses in mythfrontend.log.
One thing I noticed that's weird is that it used to be when I first
changed to a channel, the OSD would give technical data about the
channel I was changing too. One of these was "Signal" and the value
would always be at least 89% up to as much as, say, 94%. However, now
when I switch to a channel, that value is always 0%. Which seems weird,
because I can watch the channel. If the Signal were really 0%, I'd get
no picture, right?
Hints as to where to go from here greatly appreciated,
