Nobody responded (I guess it's an easy or boring problem). I'm still
having the same problems. It now seems likely to me that it stems from
the tuner card rather than myth. I've tried the following to no avail:
* Search ivtv archives
* Change frequency table in myth setup (I live in Brooklyn, NY with
cable: I tried us-cable, us-broadcast, us-cable-hrc, and, just for good
luck, a couple of other countries. I got either the same problems or
just static)
* I can manually tune the channels in myth setup, but it seems likely
that this shouldn't be necessary and would take forever to do each one.
* Looked into upgrading ivtv driver, but found I'm using 0.20 already
(installed with knoppmyth)
I've noticed something of a pattern in most, but not all channels: they
are 10 channels too high (or too low, depending on you reference point).
That is, mythtv shows the channel data for channel 22, and the picture
that actually shows is for channel 12. Again, this is not totally
consistent.
Any suggestions?
Thanks.
