The problem is with broadcasters and lack of up-to-date guide data. It's got nothing to do with the recording device as long as the clock is accurate. Part of the problem is the lag time inherent in digital vs. analog broadcasts. Set up two TVs side by side with the same station being shown, except have one tuned to the HD digital channel and the other tuned to the same channel in analog and there's a delay of at least several seconds between them. The fact that you have to ask says it all.
