Got the latest mobo and video drivers?
Got the latest flash player?
Tried flipping "hardware acceleration" in flash player?
I have a dell 1901 fp 19 inch lcd monitor and a lenovo(IBM) M52 8212 computer recently refurbished.The processor is is plenty fast(about 3 ghz) yet I still have trouble watching hulu tv shows.The action is never as good as a regular tv.There are problems with fast motion.When people speak their lips look strange like they are not moving to all the words that they speak.I thought since I was downloading at only 5 Mb/sec. that going to 25 Mb/sec would fix that but it didn';t improve it very much.A galloping horse looks strange but almost like it should.Do you think it could be because the computer is using the graphics from the mother board.I don';t have a video card.
