I bought the Basic to record both OTA and get Amazon HD TV shows because of the excellent PQ. Since starting this two weeks ago, I regularly see some pixellation at times with playback, granted its minor and not often throughout the show. The other problem is, out of about 15 shows watch, 2 have been corrupted and locked up part of the way through. This is not huge, because I just get on chat and Amazon will force a new download that ends up playing back fine. Im not sure if this has been common, or is just a Roamio bug. Resolution has nothing to do with it, because itll happen at the same point every time regardless of settings, and since a new fine will play fine, it leads me to believe its a tivo issue either when it writes it to the drive, or when it plays it back. Just wondering if anyone is seeing this, or if its been a problem on other models?
