The picture is blocky and breaking up for a couple seconds. What’s wrong?
You probably have a weak signal or one that dropped out for a couple seconds. If you record at Medium or especially Low (ReplayTV) / Extended (Panasonic), a lot of motion will cause the area to explode into pixellated blocks because there is not enough space at this speed to record all the changes. Most people use High Quality for sports. Remember, though, that some programs are digitally compressed and decompressed before they are broadcast, so you may be seeing artifacts that were present in the original signal.
