Our previous cable DVR (Comcast) had the nice feature that we could set up a recording that only kept the most recently shown episode for a series. This was perfect for news shows such as BBC World News on BBC America, where we'd always have the most recent episode on the DVR at any time -- this show is shown multiple times a day since it is an up-to-date newscast. We tried to do this on Tivo (HD) with a season pass and setting first run only, and I thought setting "1 episode" would constant erase the kept episode with the new episodes as they came in. But no, it records once, and then never records the subsequent episodes -- I want to constantly update the recorded episode. So the workaround is to keep "All episodes" -- this works of course, but you end up having to manually delete all the episodes you don't want, up to the most recent episode. This is a pain. I want the box to do this housekeeping for me. Suggestions welcome. Thanks! Stewart.
