After upgrade my Ubuntu to 11.04 I have a weird problem playing videos. See the capture from my display.

I'm getting the same thing with all of the players and video file types.

Ubuntu 11.04 64bit ATI Mobility Radeon HD 4650

Here's a screenshot (from Oli, that tries to do the video version justice):

It could be that the generic driver for your video card that Ubuntu loaded aren't fully supported by the card,are you using a 32 bit or 64 bit version of Natty? for the 32 bit and the 64 bit, the Linux driver for your card is here:

the driver has both 32 and 64 bit in it, however, I can't test it to see if it works, hope this helps!
