[mythtv-users] DVB tuning problem

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.
