Just curious, for those of you who have a DVR, Tivo, or some other digital video recording device - do you save things on there for an extended period of time? Do you just use it to record shows you might miss, watch them, then delete them? Do any shows or movies get "saved" to rewatch several times, or do you keep things cleared off? Just wondering. We've had a DVR for a couple of years now, and it usually ends up getting fairly full by the end of the TV season. We tend to keep some shows (The Office is one), and rewatch them periodically - or through the summer/until the DVD is released. Although this isn't necessarily the case with The Office, it seems like many shows get "replayed" less and less, instead replaced with some new reality show during the off months. Anyways, do you keep your DVR clear, or do you save things every so often?
