Asus G2S Dvd playback awful

Okay so I've had my G2s for around a year. It came with Vista and I installed XP on it around a month after I got it. During that time I decided that the DVD playback was absolutely atrocious, and recently switched back to Vista solely to correct this problem (I like watching DVDs in bed).

It didn't fix anything! The video is grainy and whenever there is any significant movement in the movie (like someone running across the screen as opposed to just standing there) this line shows up in the middle, like you can see it switching frames or something.

Any help is seriously appreciated.

 

Have you tried updating your video drivers?

Did your playback ever not exhibit these symptoms?

Have you tried different software packages for playback?

Sort of hard to figure out when you post so little detail... good luck

 

Updating: yes I use the modded nvidia laptop drivers

No it has always exhibited these symptoms. I even did a clean install (with the service disk that came with the laptop) and it did nothing.

WinDVD, VLC, WMP, WinAmp, Quicktime, etc etc all same problem.

Sorry about detail. I can post specs too.

 

What's your CPU usage like, and is there anything eating your hard drive in the background?

My first guess was that your DVD app isn't using hardware acceleration, but if you have the latest drivers and you're using all those diff programs that's not it.

Do you have the same problems playing back HD video from a file on your hard disk?

 

Here's the devices under DVD/CD-ROM Drives:

HL-DT-ST DVDRAM GSA-Y20L ATA Device
VH0115G WMP313W SCSI CdRom Device

CPU usage with Firefox and DVD running is between 5% and 8%
