A lot of our shows that were on ABC kept getting cut off. Some recordings are just fine, but many of our recordings (especially 30-min sitcoms) either have the end cut off, or don't start until 5 minutes before the show ends and records the next 25 minutes of the following show. We've tried padding the timer to record 30 minutes before and after but that doesn't help.
There seems to be a vague correlation to autohop since this tends to happen more often on ABC shows with autohop. ABC's revenge for skipping commercials? I've pretty much given up on many ABC shows now since I've missed so many episodes.
