So i found out what changed, it was the video and audio ids, not the freq.
Old:
KNSD HD:627000000:QAM_256:2913:2916:1707
New:
KNSD HD:627000000:QAM_256:49:52:1707
So everything I read on the wiki says myth doesn't use those id's. So I
have no clue how to get myth to find NBC again. Is anyone else out there in
San Diego having this problem too? I mean mplayer tunes it just fine, so
why won't mythtv?
I'm also having the same problem with CW, but I could care less about that
channel.
