That sounds hard to do since you can't be sure the fresh listings will  
map to the same timeslots. For example, a two hour show might be  
replaced by two one hour ones. I can imagine all sorts of  
inconsistencies creeping in and a parade of angry people when their  
shows don't record for some hard to understand reason. Wiping and  
inserting avoids all that.

Another approach could be to maintain your own version of the schedule  
table inside mythconverg. You could add some sort of --postfetch  
option to mythfilldatabase to get it to fire off a script/program  
which would reconcile program updates with your version.

Or, you could live with transferring all the new rows each time. A  
normal fill run affects today, tomorrow and two weeks from now so it's  
only 3 days of stuff.
