diagonal pixelated lines with dvd playback

I am having a problem with DVD playback using VLC media player that I hope someone can help me with. I have vlc media player installed on a windows 2k machine with a 64 mb ati radeon 7000 vid card. DVD's play very well except for one annoying problem. When there is a lot of fast camera movment or when the camera pans up/down/left/right I see diagonal pixelated lines on the screen. These kind of "slice" or break up the picture. They only form for a second or so and then go away. If camera movement in the movie I am watching is low they usually don't form. They start from lower left and travel upward to the right. They are about 2-4 inches long on a 19 inch lcd monitor. I will list what I have tried so far to correct the issue.

-searching this forum and the internet for a solution (couldn't find a similar post).
-i have tried both old and updated drivers for the vid card. (both didn't work).
-i enabled overlay video output (i don't know why i thought this would work...it didn't)
-i have tried different video output modules (direct x 3d video output seems to work the best)
-i have enabled dma access for my cd rom

if anyone has any suggestions on how I could get rid of these lines, please let me know.

Thanks.

maybe you have to enable "deinterlacing"!?

Thank you for responding. I tried the deinterlacing filter and the different deinterlacing modes (bob, x, etc...). None of those seemed to get rid of the lines. Any other suggestions??

Thanks.

If you pause playback during that problem, does it show up on paused picture, or is it only visible on moving picture?

It looks like it only happens when the picture is moving. I tried pausing to catch the problem and I was never able to catch it.

Thanks.

This is an issue in the 3D mode of your graphic card driver.

Tried OpenGL VOUT ?

Yeah I tried that...playback was very choppy with it.

Other media players work ok?
