Flash Player version 11.4.402.265 Will Not Play certain videos in Firefox version 14.01

Posted on 2012-08-22

Hi All,
I have a Windows 7 PC 64 bit running Firefox version 14.01 and Flash Player version 11.4.402.265. I can go to You Tube and play videos, but when I go to some certain websites, I get the video screen to open, but then I get "Sorry but an error has occured and cannot play video"
I have viewd these videos from these same website on several other PC's with the exact same configuration, and the videos play fine. I have uninstalled flash and reinstalled, rebooted the PC disable all extensions, tried Firefox in safe mode, but to no avail.
Any Ideas?
Thank you

    The bottom line is you use the video card on PC to watch any form of video,.
    If the video cannot handle some high def video then you can encounter problems with direct draw and or directshow
    If the audio used is AAC or AC3 you may need to update drivers for either video card and audio or install codecs.
    Some codecs can fix this.
    What if any codecs do you have installed?
    Codecs such as  FFDShow
    FFDShow is a DirectShow decoding filter for decompressing DivX, XviD, H.264, FLV1, WMV, MPEG-1 and MPEG-2, MPEG-4 movies
    K-Lite Codec Pack 9.2.0 Full, Standard and Basic
    Try right clicking the flash player screen
    settings disable hardware acceleration>test playback
    In the Global Settings tick to allow sites to save information

    The next time this happens could you please supply the URL to the page so that I can check this in Firefox.  I don't have any suggestions tight now, but perhaps may be able to ascertain the difference between a failing video and the YouTube ones that always play.

    Thanks for the advice, I have done some more testing and I think it may be a corrupted profile. I logged in under my administrator login and went to and the flash video played fine on the same PC. Looks like I am going to be changin a profile some time today. I already made the attempt at disableing the hardware accleration and this did not work either. I will let you know aftr I create a new profile. I just wish I knew what was hangin up these videos.

    Hmm I opened your link and this not the standard flash player but rather
    Moogaloop Player
    Try turning HD off that could be the problem
    Have you scanned for spyware and or viruses in your profile?

    Thanks for anyone and everyone's assistance. Deleteing the profile and creating a new one did the trick.
