So the DVDs “He’s a Bully, Charlie Brown” and “Peanuts: The Emmy Honored Collection” (AKA almost the 1980s Collection) have HD to SD remasters of most/all of the specials on them. This is all fine and dandy, but they also only have Dolby 5.1 audio tracks. I’m having trouble trying to sync up the mono tracks from the older DVDS to the better video, for consistency.

For some reason, the newer versions are all a few seconds longer. I tried lengthening the mono audio to the 5.1’s length, but it didn’t quite work. Any idea why they would be longer in HD? Is this normal for all HD to SD comparisons?
