Thanks very much for your replies! I fixed part of the video problem using a suggestion on the YDL solutions site: I was able to get the video back by using some form of CTRL-OPTION-F2 to get a terminal and executed Xautoconfig to regenerate a useable configuration file. The video now looks good, but it is still not accelerated. Is there any way to ensure accelerated video on a machine using an ATI mobility 7700 gpu?
The reason for thinking that the video is not accelerated is that I briefly get multiple window outlines when I move one Firefox window over another one. They quickly collapse, but this shouldn't happen if the video is accelerated.
