Hi!
I have a little question.
I used to run RedHat 7.0 with Linux kernel 2.4.2, XFree86 4.0.2 with
matrox latest mga beta driver.
However, I upgraded my motherboard and my CPU, so instead of having an
Intel PIIX chipset, I now have a
VIA chipset for my Socket A motherboard (Abit K7A KT133).
Everything worked just fine using Zapping before with the v4l module
loaded in XFree. I got perfect fullscreen
mode etc.
Unfortunateley, when I upgraded my system, I also got myself a nice disk
crash, so the disk is reinstalled with
RedHat 7.0 and kernel 2.4.3, XFree86 4.0.2 and matrox latest mga beta
driver (same version as before).
The XFree86 should look about the same, however now I get this strange
behaviour. About every 32:nd line or
so, lags. If there is a scene change in the picture, then about every
32:nd line is showing the last frame or a
couple of frames earlier. This means that if there was a whole white
picture and there will be a black picture,
every 32:nd line will remain white for a couple of milliseconds.
Any ideas ?

I have tried with v4l turned on and off, and when turned on,I don't get
full resolution in height, and it seems
like every odd or even frame is skipped.
Any ideas ?
Thanks
