Hi Renegade, don't know why you couldn't see the video but, I'm fairly new to Facebook and don't really understand much of it yet.
I updated all of my drivers about 4 months ago... I guess I need to do it again?
Facebook screws around with URLs in the most obscene ways (similar to Google), so it's not a surprise there.
I really don't know what the problem is for you there. I *DO* know that the general category can be attributed to video drivers. HOWEVER... I also know that different software that is running and having different devices connected can also monkey things up there and make it look like the video drivers.
If you have any devices attached, try unplugging the ones you don't use/need for a bit and seeing if that helps. Trial and error works quite well.
That being said... I do hope someone that is better with hardware than me chimes in...
