Hi, I just bought a dual g4 867/1Gb RAM/combo drive/GeForce 4MX and I'm having some quite annoying problems while playing my DVDs. The image during playback is scattered with blue and black vertical stripes. I already tried to install a fresh 10.2 with no results. The same problem exists under 10.2.4, BUT NOT under OS 9. I tried to extract a chapter from a DVD using osex and then play it, but the result is the same. Using vlc as a DVD player didn't help either.
I've also noticed some strange horizontal stripes coming out the right side of finder windows, but not always. It appears to be a random problem...
Has anyone had the same problem or know of a work around/solution?

Thanks in advance,

zmit

PS I posted some screenshots to my .mac page (http://homepage.mac.com/ivang/guest/PhotoAlbum4.html), in order to make the concept easier to understand...

I discovered another BIG problem with my setup. I think that the problem is something related to altivec because:
_When I apply an altivec enabled (for example blur) filter in photoshop 7 I get all sort of strange random colored stripes inside the image selection, BUT if I remove the "AltiVecCore" module from the plug in folder (thus disabling altivec acceleration) the filter works as it should!!
Furthermore, when I try to watch an mpeg1 file with QT 6.1 I see a bunch of stripes and dots appearing randomly on the image, but playing the same on vlc is fine. This could be a QT bug, BUT the same movie does play very well on my powerbook with 10.2.4 and QT 6.1!!
I'm afraid that this could be a major hardware problem. I hope, that someone can help me solving it!

PS I added a couple of screenshots of photoshop filter to my .mac page (http://homepage.mac.com/ivang/guest/PhotoAlbum4.html). I had to compress them on the powerbook, because Preview's compression on my dual resulted in an image scattered with dots :-(
