EDIT: I actually ended up having trouble with my Intel 865G video chip after upgrading the Flash. Please look in the Vectorbie forum to see what fixed that (or worked around it). The header in question mentions i810 and i915.
Odd. I've had no trouble watching videos on Hulu since installing Vector Linux Standard 6.0. But now I'm getting an error... "Express install is not supported on this operating system. To upgrade, please visit: Flash Player Download Center." I get this with Opera, Firefox and Chrome. The only thing that I've done recently is added Chrome and made it my default browser -- but changing that back to Firefox does nothing to fix the problem. YouTube and other flash sites work fine and I can watch Hulu on CentOS 5.4, which has older libraries and applications than Vector Linux. I'll see if there is any help on Hulu, but if I'm missing something obvious please let me know. Hulu *was* rock solid on this Vector Linux box. Thanks.
