I thought I would post about this here as I have had my Liteon 411s for quit some time. I believe I have firmware that ends in 0J. Sorry I canâ€™t think of the entire name right now. Anyways the problem I'm having which started all of a sudden with this drive is when I play DVDs that on recordable media of any type the playback(video and sound) skips but yet retail Movie DVDs play just fine. I have already done lots of steps to isolate the problem and Iâ€™m sure it is my drive now. First I checked to make sure DMA was enabled in windows, next I installed Linux with video playback software and made sure DMA was enabled as well, next I tried isolating the drive on its IDE ribbon cable as well as replacing the IDE cable although ether with a brand new one, still no luck at all. Lastly I decided to remove the Liteon drive all together from my system and install a spare sony dvd-rom/cdrw combo drive I had lying around. With that drive my problem went completely away and all dvds play back perfectly. I noticed the manufacture date on my Liteon Drive is November 2003 and Unfortunately I have no record or recollection of where I bought it from originally. It most likely might have been best buy. So it seems RMA is out of the question. Well anyways I thought I would post here and see if anyone had any ideas? Would it be worth it to get one of the DVD cleaner disk things and trying it on this drive?
