Last night I noticed on my client that selecting "LiveTV" in SageMC always tunes back to channel 1 on my STB...

When I tune to a channel, then stop watching and return to the main menu, the next time I select "LiveTV" again it tunes BACK to channel 1 (same on my server).
I first thought it had something to do with my STV customizations, so I loaded the original SageMC STV downloaded from the site, but the same thing happened. I thought then it must be some setting in the propery file, so I started SageTV with a blank one, but after finishing the configuration the same problem occured. When I switch back to the default STV, the problem goes away and it correctly remembers the last channel.
Am I going nuts ? What can be causing this ? I am pretty sure this is not the default SageMC behavior, since I am using it now for a couple of days and I surely would have noticed such a thing earlier ... or not ?
Any suggestions appreciated,
Dirk
