Good thinking!

This would be a great default functionality for an idle second tuner.  
(IE: when a PVR-500 is not recording anything, it can help improve your 
performance.)  But then the idle tuner has to answer the question: "Do I 
tune to current channel plus one or current channel minus one?"  I guess 
the natural answer is "Assume the user is going to continue surfing in 
the same direction."  But it won't help with the first channel change, 
or at least I guess there is a 50/50 chance of it being tuned to the 
right 'next' channel.

Then you also have then problem:
A PVR-500 owner always wants the second tuner to be the default for 
single recordings.  Why?  Because only the first tuner can be used for 
listening to the FM radio.  If you try to listen to the radio while the 
first tuner is recording...
