It says Radeon HD3300 Graphics. While I do not remember exactly, this sounds right, especially when I look at the Misc. Module information, which says: Card:ATI Radeon HD 2000 and later (radeon/fglrx). I remember that when I configured it a few years ago I had to select the item that included a number of graphics cards, and was labeled "[something] and later." I do not think this has been altered.
Well, I had to switch to another PC where I have an Ati card. Mine's older, a Radeon 9200 SE, using the "X1950 and earlier" driver. I didn't have Firefox installed, so I installed it. Been meaning to do it, anyway. Okay, with no Firefox addons and using flash-player-plugin from Synaptic, I went to the ESPN3 site. There's nothing currently streaming, so I picked a rerun of a girl's basketball game. In the viewing window that popped up, I waited a couple of minutes while the circular red arrow quit spinning. Then I refreshed the page, and the video started playing about a minute later.
It looks to me like you have the right driver for your video card. You could try renaming the .macromedia folder in your home directory. You'll have to enable view hidden files and folders in your file browser to see it. The folder only has settings in it, nothing necessary for running flashplayer, and should be recreated. One other thing you can try, and it's a longshot. Go to the
flash control panel page and delete any flash cookies. No, your browser settings will not do that for you. Currently, you have to do it manually.
I'm out of other ideas for the time being. All I can say is that if ESPN3 will play back on my humble Ati rig, 900mHz AMD Duron CPU with 1152MB of RAM and 128MB of video RAM, yours should also be able to. To see how much RAM your video card has, do:
lspci | grep VGA. You will see something like "01:00.01 VGA compatible controller:" followed by the card model. Using this example, do:
lspci -v -s 01:00.0. You will see two lines beginning with "Memory". The larger amount is main RAM and the smaller amount is cache RAM.
