Has anyone else had problems burning movies at higher than 4x. If I burn any faster than 2x on my new sony dru-710a then the movie has pixilation every so often. Im also wondering if it has anything to do with me burning and running other programs at the same time (causing the buffer to max and drop, max and drop). When burning a movie should I not use my computer until its finished? Ive updated my firmware to the newest version and still have the issue. oyea, the pixilation comes and goes and is never in the same place in the movie. Is the disk not being burned deep enough?
