I have an acer laptop and just put windows XP on it as it came with Vista and really dislike Vista. With XP (student version) All was well till I tried playing videos like DVD & avi files and then I started getting grid lines over the video screen. Happens with Media player, Winamp and Nero .
I thought I had a hardware problem so I reloaded a Norton Ghost of the Vista I took off and the problem was not there. I formatted the laptop and installed a fresh XP and with a fresh XP I have the same problem. I added the Ace Mega Codec pack and that did nothing. I reloaded XP again, did the updates to allow all the hardware updates to be installed and again the problem. I installed Vista again and no problem with the video. I am thinking it’s probably not a damaged hardware.
I wanted to take some photos of it and when I stopped the video to get a non-blurry background & ran a full screen print on it and pasted that to the paint function in M$, the pasting cut the size to 1/3 of full screen & showed a black background. A full screen print of anything else shows full size!
When I saved it to the drive as a jpg, the jpg came out all black with zero detail on it (shades of Dracula).
I used my camera to catch a photo of the 1/3 size presentation that pasted to M$ paint.
I also took a photo of the full screen presentation.
Lines-2.JPG is the full screen taken with the camera ( photo below on the right)
Lines-3.JPG is the 1/3 size instead of full screen as pasted to M$ paint. I took this photo with a camera as the screen print did not copy the visible screen print (Photo on the left below)
The last photo below that is blank is what was saved when I tried saving the screen print to disk. Instead of saving the full size as 1/3 as you see in the photo above, it only saved the text data which you can’t see on the reduced photo. I’ve never seen anything like this before.
Don’t see this in Vista nor do I see it in my desktop which was installed using the exact same XP install disk.
I’ve searched for all kinds of drivers for it but nothing helps & I’ve never seen this before. I may have to go back to Vista whether I like it or not…
If you have any suggestions, I sure need to know what to do. I really want to keep XP on this but I need to see videos as well.
Oh yes, I used a Viewsonic monitor to see if that made a difference and no, the problem was on the remote monitor too.
Also, when I look at an avi thumbnail without running it, there are no gridlines and when I look at a jpg in the viewer, all is well. It is only when using any kind of video that I have this problem.
