Jerky DVD playing and Burning, what's wrong?

I don't know what happened to my DVD drive:

I just burnt a DVD and it took 70 minutes to burn about 3GB files. While it was burning, the whole system appears to be jerky and the sound playing is interrupted.

Then I played a DVD movie and the play back is absolutely jerky as well. After few seconds the playback will pause a little and the sound is interrupted.

What's wrong with my DVD drive? I only time I mistreated it is that I ejected the DVD when it was playing.

 

Does it play everything else ok? If every DVD is jerky then you have probably have a bad dvd drive. If it only happens to this dvd, then something went wrong with the burn process that caused the problem. The disk was was possibly:

1. a bad disk
2. a low quality disk. Some brands are not good at all.

If it's not a hardware problem, I would burn it again using a different disk/brand.

 

I just used Nero DVD/CD speed to test the speed, the reading speed is only
1.16x.

I tested with a DVD that ran smoothly a few days ago, still get the jerky playback.

I am almost certain that the reading/writing speed just becomes unbearably low regardless of the discs I am using. What gives?

 

Go into Device Manager and check your IDE channels.

Check what mode they are in such as Ultra DMA, or PIO.

If they are in PIO then uninstall the IDE channel and restart the computer and let it reinstall them.

Thank you. I don't know why MS mysteriously changed the IDE mode into PIO.
Now it very smooth.
