Here is the solution I found

SDL Development

To correct my problem, I first switched from a double buffered surface to a
simple one. As a consequence, I used SDL_UpdateRect instead of SDL_Flip. But the
most important thing is, I first drew my tiles using the dot per dot (and slow)
method, and then, once the screen was filled, I could use the fast blit method
(using SDL_BlitSurface.

Hi,
I recently moved a program I made from one computer A to another computer B.
The program plays videos using SDL and SMPEG libraries.

For some reason on the new computer B, the graphics look like this:
http://onsight.id.gu.se/~sue/image.jpg

Whereas they should look like this:
http://onsight.id.gu.se/~sue/original.jpg

If I use mplayer on computer B, the videos play just fine, so I am assuming it
is a problem with some part of my code for SDL. But could I be wrong?

Any ideas?

Thanks_____________________________________________

Based on the images my first guess would be that your code works on the
video mode you got on A, but that you get a different video mode on B.

thanks, it was fixed by changing the bits per pixel in the video mode.
