OK this is really weird.
I tried changing cycling through the X11 screen resolution as I ran a movie at full screen.

(Note the picture size itself remains 1280x1024, just the screen resolution changes meaning that more of the image goes off screen)

Here are the results:
1280x1024: jaggies
1280x960: no jaggies
1152x864: no jaggies
1024x768: jaggies
800x600: jaggies
640x480: jaggies

I am using the following stanza in my XF86 config:

Section "Screen"
Identifier "Screen0"
Device "NVIDIA GeForce 4 (generic)"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 16
Modes "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x48\
SubSection "Display"
Depth 24
Modes "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x48\

It might be interesting to check what happens if you *start* at a resolution other than 1280x1024 or if you change the pixel depth.

I also should repeat my other observation, that when I manually resize the frame it stays ok until I get to about 2/3 of the full 1280x1024 screen size when the jaggies suddenly appear. Seems like a very binary type of thing.

This is all so weird!!!

I am also curious that you and I both have the problem despite having very different machines, graphic cards, and linux distros, while at the same time *nobody* else either on these boards or via googling has reported the problem.

I also wonder whether the reason that playing another video first works is that perhaps the first video uses hardware acceleration whereas the 2nd video uses software emulation. (???)
