Yep, me also... The MPEG4 LILs are by far the worst. And this occurs on both the HR20-xxx and the non-DVR hardware : H20-100 .. so has nothing to do with the buffer/recorder in the HR20 ... But I really believe it's the MPEG4 "spotbeam" technology that is the culprit. But I'm no technician. Is CNNHD Mpeg4 ???
