    Flash-Based BBC h264 Videos Freeze After 8 Seconds



      I like to view BBC news videos since March on my new Desktop Windows 7 64 bit Pro system.  For about 2 weeks now, I've been having trouble viewing about half of these videos.  Half play all the way through fine and the other half freeze after 8-10 seconds.  I have a CAT 5e 7 mbit cable modem connection so speed is not an issue.  My Wi-Fi connected Windows 7 Home Premium laptop uses the same router and can play the same videos with no problems.


      On my Desktop, this freezing happens on both FireFox 12 and Internet Explorer 9.  I did all the usual things to try to fix the problem.  I cleared the caches on both FF12 and IE9.  Yesterday, I uninstalled both the Adobe Flash FF12 plug-in and IE9 Active-X versions and reinstalled with the latest version, 11,3,300,262.  Today, I upgraded to the latest version, 11,3,300,265.  Nothing has solved the problem.


      Here are the specs for the BBC Flash-based player:

      This video plays OK:

      The only difference I noticed was the initial screen size of the video.  On the problem videos, the size is bigger than the OK one.  I assume the BBC videos are h264 encoded.  On both my Desktop and my laptop, I have 2 msmpeg2vdec.dll files.  1 in C:\Windows\System32 and another in C:\Windows\SysWOW64.  They are both v6.1.7140.0.  On both my Desktop and laptop, the sizes are different, 2.52 MB & 2.03 MB.


      I am using the latest nVidia driver v301.42 which I installed 5/30/2012, over a month ago.  The only recent change which happened to my system on 7/4/2012 was my Norton Internet Security 2012 subscription expired.  NIS2012 then disabled itself and activated the built-in Windows firewall.  3 days ago I uninstalled NIS2012.  I also used the Norton Removal Tool.  I then installed a new NIS2012 with a new legitimate key.  However, I am still getting this freezing and I don't remember if I got this freezing before 7/4/2012.


      On both FF12 and IE9, I can play Hulu, YouTube, Yahoo!, and Amazon videos with no problems.  When you right-click on any of these other flash players, nowhere does it say "h264."


      My questions are:

      1)  does the Adobe Flash Player, for both the FF12 plug-in and IE9 ax players, use the Windows7 CODEC?

      2)  Which file is the h264 CODEC, is it msmpeg2vdec.dll or something else?

      3)  Will installing a new CODEC pack fix this problem?

      4)  Is there anything else I have overlooked?  Is there anything else I can do to fix this problem?
