When I want to delete a series of a program I have to go to each show to delete... why can't I delete a whole series at once? (i.e.. the kid taped every "The Simpsons" known to mankind- I want to delete them all). Second, when I get to the end of the DRV recorded program - why can't it allow for back up instead of just delete or start over. Sometimes I miss the last few minutes and I want to back up.... Instead I have to start over and ff all the way through.
