Yes, I have noticed weird recordings. As to whether they were on the HR20 and/or HR21 I don't recall.vernonator said:I have an HR20 that for the last month or so has been recording things seemingly at random. Not every day, but once or twice a week I will have a recording of some bizzare show. At first I thought maybe it was the kids hitting record on the guide, but the last one was on a channel that I don't SHOW in the guide - and it recorded in the middle of the night when no one was up to manually select it (unless the cat was watching it). Has anyone else exprianced this?
