| 325662 | 2005-02-17 10:36:00 | DMA has been enabled all along (I'm sure I've said that before). Device Manager says DMA is set to Multi-Word DMA Mode 2. | pmchapman (2942) | ||
| 325663 | 2005-02-17 10:39:00 | Yes, you said it in your origional post. What happens if you try playing DVD's in DivX Playa? |

| 325664 | 2005-02-17 10:53:00 | DMA MW 2 (this is only 16 Mbytes/sec, not the suspected 33 or 66 in UDMA), any other devices sharing this channel (sometimes CDRW can)? I would suspect the drive should be capable of using UDMA4 if recent (66Mbytes/sec) and can only be achieved by what you say you have, a fast ribbon cable 80-wire/40pin? Although this may not be the problem, you may need to update your chipset drivers and IDE controller drivers. I would then test the drive out with DMA disabled, and put in in PIO mode, probably 3 or 4 if possible (although slower, PIO4 is same as DMA MW 2) it's to determine whether DMA is at fault or not. If still the same results, it maybe something else, maybe windows xp needs performance tweaks, disable those prefetching programs, in case it's trying to cache the whole thing. Kame. |

| 325665 | 2005-02-17 10:59:00 | I have the updated drivers. I have also tried an older set of drivers that VIA reccommends for older chipsets such as my own. DMA turned off has made the problem even worse. It is only a 2X DVD-ROM drive, so I don't think that Multi-Word 4 would make much difference, as the drive can barely spit out enough data to fill up the bandwidth of Multi-Word 2, especially since this same drive was flawless under 98. |

| 325666 | 2005-02-17 11:06:00 | The drive should still be ATA 33, so 33Mbytes is still a considerable difference. What I suggest is delete it from Device Manager, restart or just rescan the device manager and get it to reload it over again, and try it again. Or switch IDE channel or slave it or master it off another device. Other than finding out the results from this, I think we're running out of options. KK |

| 325667 | 2005-02-17 11:29:00 | Try to find what is causing the CPU to run at 100%, I am sure that will cause chopiness, it does on mine. | zqwerty (97) | ||
| 325668 | 2005-02-17 18:52:00 | CPU Usage rockets on my 800Mhz when playing DVD's to about 80% On a 533Mhz it will sit at 100% the whole time. Thats just it working hard to decode the mpeg2 video. |

| 325669 | 2005-02-17 20:49:00 | under the video settings in powerdvd have you tried enabling hardware acceleration? When playing dvd's on the computer I find this drops the cpu usage considerably |
