new lite-on conmbo drive plays choppy video full screen

[jonno]

I just replaced my old samsung dvdrom with a new lite-on combo drive. It's black and matches my dell. Otherwise it's a disappointment. It burns CDRs fine, but when playing dvd's, the picture is smooth in a small window(60% of screen); if I go full screen the action is choppy, like frames are missing. The software that came with it is PowerDVD5 which also installed DirectX 9. My old samsung used PowerDVD4XP; that won't work with this new combo drive. Perhaps a bundling thing.

I have XP Pro, Pentium 2.8C 512DDR, Matrox G550, 17"CRT

Any ideas? Do you think I have a faulty drive? Neither Lite-on or Cyberlink have answered after 48 hours.

Thanks, Jon

might check and see if DMA is enabled for the drive, if not, then enable it.

If you have the SOHW-1633s make sure you have the latest firmware installed. If that doesn't work could be RMA time.

It is the SOHC-5232K firmware is NK0E. I just downloaded firmware NK0H. 2 revisions later, but I doubt that's it. DMA is always enabled in XP right?

FIXED. Works great. The problem was found layers deep in my video card settings. Had to check bus mastering. Never knew the option was even there; thought it was a given. Works like a charm now. better than the old samsung.

Glad you got your Liteon working, I have the same model but with a different vid card that uses DMA. What media are you using with your Liteon that gives the best burn, I have as yet to do this so would appreciate your findings.

I have used Fuji Japan (Taiyo Yuden) that I cant find anymore with great success. I bought some Maxell 48X at Office Depot that were really cheap; think I got 100 for $20. One of the less fancy CDRs out there. they burn at 48X perfectly. So I think you're probably OK with any decent media.
