'fraid not. I've updated to r7376 on the backend and done some more 
testing, with inconsistent results.

Using this command line on the backend:-

/usr/local/bin/mythbackend -v record,channel -p 
/var/run/mythtv/mythbackend.pid > /var/log/mythtv/mythbackend.out 2>&1

I get these results on three tests:

1) Starting channel 7. I go into/out of tv 3 times OK. Change to channel 
2, exit, and go back in OK. Exit and go back in  fails.
2) Starting channel 2. I go into live tv OK. Exit and go back in fails.
3) Starting channel 2. I go into live TV OK. Change to channel 7. Exit 
and go back in OK (twice). Change to channel 2. Exit and go back in OK. 
Exit and go back in fails.

Using this command line:-

/usr/local/bin/mythbackend -v record,channel -p 
/var/run/mythtv/mythbackend.pid -l /var/log/mythtv/mythbackend.out

1) Starting channel 2. I go into live tv OK. Exit and go back in fails.
2) Starting channel 2. I go into live tv OK. Change to channel 7. Exit 
and go back in fails
3) Starting channel 7. I go into/out of tv OK. Exit and go back in fails.

And finally with this command line:-

/usr/local/bin/mythbackend -v record,channel

1) Starting channel 7. I go into/out of tv OK. Back into TV OK. Exit and 
back into TV OK. Exit and back into TV fails.
2) Starting channel 7. I go into tv OK. Change to channel 2 OK. Exit and 
back in OK. Exit and back in fails.
3) Starting channel 2. I go into tv OK. Exit and back in fails.

Looks to me like the presence of '-l' doesn't really have any impact. It 
also looks like it doesn't matter which channel it is (which I had been 
thinking was the case.)

Cheers,

Jon
