[ NNSquad ] Workaround for new YouTube "black window - no video" problem


Greetings.  I've been getting reports of a recent problem affecting
increasing numbers of systems when attempting to play YouTube videos
*on the main YouTube pages for those videos*.  The symptom is that
audio plays, but the image area remains black.

Research indicates that this issue began a few days ago and appears
suddenly on affected systems.  Most reports of this that I've seen
suggest that this is a Flash-related problem possibly limited to
Windows systems with particular display drivers.  I have one report of
a similar problem on a Google TV (Logitech Revue) system -- I have
*not* been able to confirm this on my own LR unit so far.  However, I
do have one Win 7 system here myself that now has succumbed to the
problem.  Earlier in the day it was playing YT videos just fine, later
they were all black on YouTube main video pages.

I emphasize "main video pages" since embedded YT videos on other Web
pages do not seem to be affected by this problem, again suggesting
that the issue relates to the various YT players themselves.

There *is* a workaround to restore main YT video pages functionality
until Google fixes this (and they *are* actively working on it).

The trick is to turn off the Flash hardware acceleration.  Normally
you would do this (on Windows) by right-clicking on the YT video
display surface, choosing "Settings" (not "Global Settings") and then
unchecking the "hardware acceleration" option.

Unfortunately, when this (black video) problem is present, the
"Settings" option is grayed out.  The solution is to manipulate the
settings on an embedded video page where the video is still appearing.
Any should suffice (e.g.: http://j.mp/h23Tkz - my latest blog entry).

Once you've turned off hardware acceleration there, the main YouTube
video pages should display proper video again.

Obviously, you don't want to leave hardware acceleration disabled
indefinitely, so I recommend turning it back on at intervals so you'll
know when this problem has been retired to the bug graveyard.

I'd be interested in any reports that provide additional information
about this situation.  Thanks.
