Some On-line video not playing - A Flash problem?

Resolved question

I'm having a problem with some video (on-line) not playing - nothing, just a solid black screen.

For example, I go to the Comedy Central site, select a video, and the screen stays black. It sometimes shows a spinning gear for a brief moment and then it disappears.

No indication of any kind that I'm missing some plug-in or need to update something - the blank screen just remains blank.

I can play TV programs, pressed play, and it works fine - I get a short preview. I've visited several news sites, watched videos. No indication of why. Other videos that I have on disk (TV programs etc) run fine.

I've tried various sites in an effort to determine the nature of the problem, but it's beyond me at this point.

I have gone through Adobe's Flash Control panel site, set and reset various storage/security setting - no change.

I have cleared out the caches and run disc permissions repairs.

(My wife's macbook works fine and plays video from CC and other sites where mine won't.)

I just upgraded to Lion and there is no change.

iMac24-inch, Early 2009
Processor 2.66 GHz Intel Core 2 Duo
Memory 4 GB 1067 MHz DDR3
Graphics NVIDIA GeForce 9400 256 MB
Software Mac OS X Lion 10.7 (11A511)

I would greatly appreciate any suggestions
