[mythtv-users] Channelchanging after upgrade on an external satelite reciever

[Per Jørgensen]

Hey Group.

I have my Myth upgraded to 0.21, which is almost working perfect.
I have an external satelite reciever connected to my PVR500.
I have made a script in bash that worked perfect under 0.20, but after 
the upgrade I'm starting to get a error on and don't quite know what to 
do to solve this.
The Dreambox haves a webinterface - which I use for changing the 
channels. called from a normal bashscript!

The startup log:

The last lines are the one that makes me wonder.
Especially carse this haven't been a problem before.

well - When calling the script for an external tuner change are the 
logfiles like this:

Since the script aren't called at all, the channels arent changing.
The script can be seen here http://linux.pbj-design.dk/scripts/ch_chan.txt
So can someone tell me what to do - to make this work again. Carse the 
picture's is there and working great - but cannot change the channels. 
unfortunably. !
