[mythtv] Re: Ticket #802: DiSEqC confuses channel changing with LiveTV

[Luis Ochoa]

Could this be why, while in LiveTV, if I try to change to a channel in
a different port (I have a Tone Switch, which by the way doesn't
switch anything, I had to play with the LNB LOF switch value to get it
working, 0 for 22khz ON port and 99999999 for 22khz OFF port...but
that's a different issue) say from a channel in 119 to a channel in
110 I get a message to the effect that all the cards  are in use, that
I need to stop a recording (although nothing is being recorded) ??

This is with the newer code, the older 0.18.x code switches ports fine.
