[mythtv-users] Problem changing channel

[Jesper Rasmussen]

Hey there, I have been searching the archive and other places, and it 
seems i have hit a FAQ, but all the answers i have seen doesnt seem to help.
When I change the channel (pg up or down) it pops up with empty osd and 
the time.
If i press a number, the number is displayed, but it keeps showing the 
same channel.
Also when i record a show either manual or from epg still the same 
channel is recorded.

Does a db schema document exist somewhere, describing the tables and 
columns?

thanks for any input!

Jesper
