You probably have not seen anyone reporting the exact same problem as you. All three crash reports have the same crash signature and as currently ranked 67 it is not the commonest of reasons for a crash.
I hope you enter your email contact information when reporting crashes. I note you see this crash when using videos, others may possibly see this crash in other circumstances.
You have already tried the obvious, attempts at a fix so it is now down to wait and see, maybe developers working on the bug will report something or fix it.
Did you try my suggestion of installing portable ESR ?

    Mov is a container format, you'd need to look at the codec used by the movie file inside the container to know whether it will work with the Apple TV or not.

  • Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file

    How do I fix this?

    That would probably be a question best taken up in on a site for Windows support questions. Not knowing anything about the movie you're trying to play, all I can suggest is to confirm that the format of the movie you wish to play is supported in your version of WMP. If it isn't, you'll either need to convert the movie or use some other player software.

    Hi fishonfoot,
    Thanks for visiting Apple Support Communities.
    You may want to use this article as a guide to determine if the songs are on your computer:

    If the missing songs were purchased from the iTunes Store, see this article for the steps to download them again:

  • Windows media player albums are upside down on Firefox, why and how fix?

    In IE 10 albums and playlists in Windows Media Player are listed from 1 - whatever. In Firefox they are listed say from 18 - 1 and are played in that order. How can I get these right side up?

    If there is a column heading above the track numbers, try clicking it once or twice to reverse the order. This works in a lot of programs, but I'm not sure about the in-browser media player. Actually, I'm not sure how you were able to display an album in a plugin in Firefox. Is this on a particular website?

  • Installing Adobe Flash Player 10.0.42 Plugin for Firefox 3.5.7

    I currently have Firefox 3.5.7 installed and am trying to access a site that requires the current version of Adobe Flash Player (10.0.42). When I download and install it, the website still doesn't recognize flash player being installed.
    I go to Adobe.com, make sure I am downloading the one for WinXP/Firefox and install it, then it says that it is successfully installed. However, when I try to access the site, and it says that the current version of flash player is not installed, with a link to the adobe site to download the latest version (which I already did).
    I have tried uninstalling the flash player, from both Windows and Adobe's uninstaller, and reinstalling with no success. I have even tried uninstalling/reinstalling Firefox, still nothing. For fun, I tried updating IE, and it works fine, but I REALLY don't like IE.
    Another note: when I uninstall Flash Player, it doesn't remove it from my machine (add/remove program list), even when Windows asks, "Adobe ... is already uninstalled, would you like to remove it from the list?" Additionally, when I go to Adobe's Flash Player version tester site, it reports that IE is running version 10.0.42, but when I access it with FF, it shows a link to download the latest Adobe FP.

  • Windows Media Player cannot play the file because the required video codec is not installed on your computer

    I can not find solution to the issue "Windows Media Player cannot play the file because the required video codec is not installed on your computer" while attempting to play the file with *.wmv extension. Some computer fail in spite of said missing codec
    being present according the windrows media player in Windows 7 box

    If Rashid's link does not resolve it... consider the below:
    A)  As of this writing, the codec for GoToMeeting webinar recordings ("G2M4" codec) was only mentioned in *one* web page, of about 10 Microsoft web pages I read, to resolve this problem (and that codec is not included, yet, in their diagnostic tool),
    so if you're trying to play a GoToMeeting webinar, simply get the codec for it from their site:  http://www.GoToMeeting.com/codec
    B)  If Windows Media Player (WMP) will not even open the file, you won't be able to get the 4-character codec's name (like "G2M4") from WMP.  But VLC's media player will tell you that code, even when it fails to run the video.... and then you can
    search the internet for it. 
    C)  The problem sometimes is not actually a missing codec.  Other things that have helped others, some from: 
    http://answers.microsoft.com/en-us/windows/forum/windows_7-pictures/the-windows-media-player-12-could-not-play-the-wma/bb823460-44df-4e8d-ba2c-42ec0e111e5a?page=3
    (1) running the System File Checker (SFC.exe),
    (2) opening WMP first (running both the 32-bit and 64-bit versions) then opening the file from inside them,
    (3) confirming that WMP was the file association for WMV files,  
    (4) Control Panel -> Hardware and Sound -> Sound, selecting my audio device, and looking for a "5.1" setting (I didn't have one), to change to "stereo",
    (5) checking Tools\Options\Devices\Speakers\Properties\Speaker Properties\AdvancedPlayback\ Speakers /HP\Properties\Advanced\Default Format, to select "CD or DVD Quality" (if that setting appears for your device),
    Good luck,

I've installed it many times and still nothing. Please help--getting very frustrated that I can watch YouTube videos on my smartphone, but can't on my computer which costs 12 times as much!!!

    I've installed windows media player for mac but some sites still ask me to download, have you encountered the same problem before?

    Most sites require Windows media player version 10 or 11. The latest version available for mac is version 9. So are still not able to play the content.
    An alternative is to download Flip4Mac from http://www.flip4mac.com

    Does the same file play normally in iTunes?  Do other audiobooks play normally on the iPod?
    How does "borrowing" work?  Does it require use of another app, other than iTunes, to get it on the iPod?

  • Windows media player stop working after upgraded from firefox 6.02 to Firefox 7.01 yesterday.

    windows media player stop working after upgraded from Firefox 6.02 to Firefox 7.01 yesterday.
    the plugin for win media player is already installed and working fine in FF 6.02 before upgrade. i have Google this issue without any result so far. so i reinstalled the old version 6.02, until fix is found.
    anyone has the similar issue with Firefox 7.01 in Win 7 32 bit ?

    The issue was not with FF 7.01. VLC player version 1.11.1 is conflicting with windows media player when FF 7.01 tries to play media files! Which was not happening before in FF 6.02.
    VLC and plugin media player need to be uninstalled first, then uninstalled FF 6.02. Install FF 7.01 and then win plugin media player again.
