    mpg files no longer play in QT on Snow Leopard
    Hi there,

    I'll try and give a brief synopsis of my issue.

    Since updating to Snow Leopard, mpgs will not play in QT 7 or QT X. Specifically, the mpgs that won't play are H.264 and AC3 in mpeg 2 format (excuse my terminology if it is incorrect).

    When I say they won't play; in Quicktime 7 the application will launch (but not bounce on the dock) and eventually load a window playing as if it was a silent mp3 and then start not responding. In Quicktime X it will report "The document *.mpg could not be opened" or indicates a system error "The operation couldn’t be completed. (OSStatus error -12710.)" this has 0 hits on Google.

    I have tried reinstalling Perian, my Quicktime Mpeg2 component and both versions of Quicktime to no avail.

    These files will still play fine in VLC, and on my Playstation 3 but will not load properly in Mpeg Streamclip. As a side note, I only noticed this problem when trying to create a reference version of the file to iTunes using VideoDrive.

    This is driving me insane!

    Not sure what's happening there. I had similar issues with QuickTime X after upgrading to SL until I remembered needing to install the QuickTime MPEG Playback Component. You've already tried that though so unless the install did not proceed properly.

    If I have any files like that I will give it a try and see if I get the same results.

    Yes, it is strange! What is stranger is that I didn't need to use the Mpeg 2 component before SL. I suppose Perian covered those codecs?

    I recently converted from Windows XP to Mac Snow Leopard. None of my MPEG-2 videos would play. So I bought the QT MPEG playback component and the videos play allright but the AC3 audio does not. Now I don't know if the QT pro will play the video and audio or not. So don't buy the QT MPEG player, but if you want one cheap I will send you mine. I wish I could go back to before I bought the Mac and just got a new PC with Windows 7. I know the stress would not be this bad and I would have saved $1000. Who can save my sanity and judvard's and tell us how to play our MPEG videos and with sound. I downloaded the Flip4Mac and can play .wmv videos and with sound. Someone help! Thanks so much.
