If I have a show set to record on a specific channel at 2 pm and I have the previous show paused (e.g. the 1pm to 2 pm show) then the DVR automatically jumps to the second show at 2 pm (thus losing whatver was stil buffered of the previous show). I would expect this to happen if the seond tuner was busy but it's not. Ironically his does not happen if the second show is on a different channel. Has anyone else observed this odd behaviour?
