[mythtv-users] MythTV not tuning or changing channels

[John Harvey]

Neither. It makes the ioctl calls directly itself.

I was having similar problems last night but set both
chanid & frequency to be the same and then it worked.
I dont think this is correct and couldn't work out
what i'd done to fix it. 
I'll have more of a play tonight and try to get to the
bottom of what i did to get it to work.
