I'm experiencing a strange problem with about 5% of my dvds. Regardless of whether I watch directly from the disc or rip and watch from the hd, these movies have a black border around them. I can select zoom 135% and the video is then normal, but it would be nice if it happened automatically. Even stranger, some, but not all, of the same dvds do not play scenes in chronological order; the movie skips from point to point like a Tarantino flick. Any ideas why this might occur?
