[mythtv-users] Switching channels only possible while mythfrontend is "offline"

[Thomas]

One more fact I have just found out: switching channels works fine as 
long as I stay within one bouquet (frequency) of DVB-T. For example 
channels 4 and 8 in my setup are on the same frequency and I can switch 
between them without problems. But switching to channel 3 (different 
frequency) requires a frontend restart. After the restart I see channel 
3 and can switch to other channels on the same frequency as channel 3.

Strange, isn't it ???
