To use your hd cards whenever possible you should set the card priority 
of the hdhr to higher than your pvr-250. This will cause the logic to 
record anything available in both sd and hd as hd and will make your 
hdhr be the primary recorders and the 250 as the backup. You can still 
have your per-program priorities too. That is how I determine which one 
in a conflict should be recorded. I set Cops to -2 so that it loses to 
anything else.
