[tlug] No video playback in Iceweasel

[CL <az.4tlug@example.com>]

I'm out of ideas here and need some help.  I have no video playback 
capabilities in Iceweasel and haven't for the last 4~5 versions.  I am 
installing the iceweasel-aurora version from wheezy-backports at 
http://mozilla.debian.net/ and am currently at v.35.0a2 (2014-11-11), 
but the problem has been occurring since v.28.0, or so.  I usually just 
cut and paste the link into Firefox in my WIN7 VirtualBox, but that is 
getting old, even for a patient (lazy?) person like me.

Right now, listed video drivers are:

Shockwave Flash 11.2.202.406 (the last supported version for Linux, IIRC)
VLC Web Plugin
Skype Buttons for Kopete

There is also a message that Open H264 Video Codec Provided by Cisco 
"will be installed shortly"  It's been promised for so long I keep 
wondering whether Cisco has been acquired by Microsoft.

I've tried killing all add-ons and just starting the video players, then 
adding the add-ons back one at a time to see which one is killing the 
video, but the video doesn't start with all other add-ons turned off, 
either.

I've tried completely stripping Iceweasel from the HDD and installing 
just the video players but that hasn't led anywhere, either.

I've tried installing alternative players.

Still no joy.   Looking for other ideas.
