So I moved to Arlington, VA from Bethesda, MD (both Comcast). I used to have the HD Motorola (DCT6412 or something) and now have the 8300HD. I have a bunch of shows set to record all instances of a show, for example MythBusters. It worked fine for a while, but now EVERY time it tries to record a mythbusters I wind up with about 5 to 10 pieces of the show that are anywhere from 1 minute long to 30 minutes long and even worse is that it messes up the schedule for ALL future recordings. Right now this only seems to be happening on mythbusters and no other shows but it is REALLY irritating. Anyone had anything like this?
