DVD/CD choppy

Question

I was playing a dvd today, but it was running extremely choppy and slow. Bot video and sound was like it was buffering extremely slow or something. I have tried watching the video in several media players(cineplayer and wmp) but both have similar results. Also when the video is playing it is almost like it is lagging the computer greatly. The mouse curser lags, and all animations begin to lag. Even when I minimize with the video playing, it seems lagged, but once I pause or turn off the video it is fine. Also I find that when more is happening on the screen(faster movement on the screen) then the choppier the video becomes. This happens with both CDs and DVDs, but more so with DVDs as there is both audio and video. It is almost as if the buffer is unnable to go fast enough as the playback of the disc, but that would hardly make sense.

Check that your drive is in DMA mode and not PIO mode here .......

Start | Control Panel | System in classic view | Hardware tab | Device Manager

Click on the (+) next to IDE ATA/ATAPI controllers. Right-click the channel
the DVD drive is on and select Properties. Click the Advanced Settings tab.

OMG wow that worked. Just in case anyone else gets this problem, what I did was uninstall the secondary IDE and then rebooted the computer. And once windows started loading up, my desktop said that new hardware has been found. Wait until everything is booted up and the new hardware should be installed and ready to be used. I did not have to change anything after this.

A poor quality DVD caused my DVD drive to reset from DMA to PIO. Editing the registry (deleting the entry), and rebooting solved the problem. Thanks guys!

Exact same thing happened to me on my Dell XPS M1210, but only showed choppy audio/video playback when I tried playing DVDs through the Windows Media Player.

This is what I did.
01. Right click the My Computer icon on the desktop.
02. Choose the Hardware tab.
03. Choose Device Manager.
04. Expand IDE ATA/ATAPI Controllers.
05. Right click Secondary IDE Channel
06. Choose Uninstall.
07. Select Ok.
08. Select the Start tab on the desktop.
09. Choose Settings.
10. Choose Control Panel.
11. Choose Add Hardware.
12. Choose Next.

My laptop automacially found and installed the hardware and enabled the DMA. It was previously reset to PIO (when I checked) and I had no option to change it.

Oddly enough, I have a region-free program which loads on startup that usually ensures my laptop is set to DMA, but it was not able to fix the PIO change.

Anyway, this worked perfectly. Thanks for the article and information.
