I had the same problem for a while. Turned out the bttv driver wasn't detecting my 2 WinTV Go card's tuners correctly.

I figured this out by running dmesg. Scroll up until you see lines similar to the following:

bttv0: Hauppauge eeprom: model=29440, tuner=? (-1), radio=no
bttv0: using tuner=9

Note that on the first line, it's failing to detect a tuner properly. To fix this, in the file /etc/modules.autoload.d/kernel-2.6 (I run Gentoo on a 2.6 kernel, your distro/kernel might be different), I added the line

bttv tuner=9,9

This loads the bttv driver at startup, and tells it that both cards use tuner 9.

To figure out what tuner you have, you can go to http://www.mind.lu/~Eyg/ftvco/ and download the utility.

Hope this helps.

This just started a few days ago, but for some reason,
mythtv will only show channel 52 on livetv or
recordings, despite changing the channel(the number at
the top saying it's channel 47 or 58 or whatever, and
menu at the bottom  saying the different channel name
and show).

Help?
