Recently I went to play a DVD in my comp just recently and found that it skips or is choppy during playing. I thought mayby it was something to do with windows. Check DMA and suposedly its enabled. So I throw an spare hd in my system and try playing dvds under ubuntu linux with ogle and still the choppyness is exactly the same. I also made sure DMA was enabled here as well in linux. Then I go wtf and try a spare dvd-rom drive i have lying around and different ide cables. Still the same result. Then I upgraded by bios thinking mayby the version I had installed had a bug but that didnt help as well. I'm at a complete loss as to whats causing this problem and I'm seriously geting ready to chuck my pc in the trash bin outside or something drastic like that I dont supose anyone has any ideas?

Hi there, do you have a CD-ROM drive on the same IDE channel? The thing about IDE is that if you have two devices on the same cable then they'll transfer data at the rate of the *SLOWER* device. So if you have a CD-ROM which is ATA 33 and an ATA 120 hard drive running on the same channel, the hard drive will only transfer at 33 speeds.

I think DVD's have quite a higher data transfer rate than normal CD's so this could be the problem.


The system is plenty powerful to run DVD smoothly, so I'm pretty sure it'll just be a setting that's not right.

Thats incorrect unless you have a 40 strand IDE cable on that hardrive

So how can you tell the two types apart? 40 & 80 strand, that is....

The ATA 66 cable (80 strand 40pin) has small strands, they're quite easy to tell by looking at them.

Check your DVD software to see if it has hardware acceleration enabled too
