I've got a problem that I have been fruitless in finding any information on, so I thought I would throw it out here to see if anyone has any insights.

I have 2 clear QAM capable tuners. I am watching live TV from 7PM to 9PM on one clear QAM channel, and have set up to record another clear QAM channel at 8PM.  Just before 8PM, VMC pops up a message saying it needs to change channels to record my show.  This is quite confusing, as there is another available tuner.  If I say OK, it will change to that channel and start recording.  I then decide I will switch back to the channel I was watching live.  Clicking on the channel in the guide does nothing.  I edit the channel, and change the ordering of the tuners for that channel.  Then VMC switches to the channel, and the recording on the other continues.  Shouldn't VMC be doing this automatically?  If its first choice for tuner is in use, and there is another that will work, use it?  I don't think I have this problem with the analogue tuners (can't recall this problem with them....)
