Thanks, but I am already running this every night from cron so that
will not help.
But this is the kind of *constructive* discussion needed here. Thanks!

Sounds too good to be true ;-)

I again noticed that the wait MyhTV does for the next channel digits
confuses my perception of long channel times. As I mainly am using only
channel number 1-6 every press of a number to get to the channel suffers
from that timeout.
a --/- button might be the solution? As in the "old" TV:s.
Is the timeout adjustable?
