I've noticed that many of my recordings on the HR21 are starting a few seconds late, maybe 10-20 seconds. Not much, but enough to, on occasion, cut out a little bit of dialogue at the beginning of the show. Is this happening to anyone else? Is this a time issue with the HR21 or are some stations starting their shows a little early (perhaps to fit in more ads?). Can I set the recording a minute or two early without causing conflicts if I have two shows recording prior to this one? Thanks.
