I am running quicktime 10.2 on OSX 10.8.2

I have Compressor 3.5 installed as well as DVD Studio Pro 4.

I have recently upgraded to this new machine (Mac PRO 2X 3.06 6 core xenon)

I cannot view M2v files in quicktime player.  I used to be able to on my old maching running qicktime 10.0 as well as having quicktime 7 installed.

I see the quicktimempeg2.component installed in my system/library.....  and I am confused why then no longer play on this machine. 

the files I create Here I can see on the old machine as well as this machine in DVD studio pro.

I should not have to go grab a 3rd party app to view these files.

 

thank you

    I cannot view M2v files in quicktime player.

    If you are referring to properly encoded MPEG2 video content in an M2V file container, then both the QT X v10.2 Player and the QT 7 "classic" Player (with the QT MPEG-2 Playback Component installed) should be able to the M2V video file data.

     

     

    I see the quicktimempeg2.component installed in my system/library.....

    This component only supports MPEG-2 content in "classic" QT apps like QT 7 or MPEG Streamclip. The QT X v10.2 player supports MPEG-2 content using a different component installed as part of the OS v10.8 Mountain Lion OS installation. I normally use the QT 7 Player for viewing M2V files paired with AIFF elementary streams (or MPEG Streamclip for M2V video paiered with AC3 elementary audio streams) because the QT X player does not automatically open elementary audio streams paired with M2V files. (I.e., if you have paired M2V/AC3 or paired M2V/AIFF elementary streams, then they must be manually opend in separate players for QT X playback.)

     

     

    the files I create Here I can see on the old machine as well as this machine in DVD studio pro.

    I should not have to go grab a 3rd party app to view these files.

    Since you have not explained what you mean by "create," it is difficult to tell if you are also having a "content-container" problem here. For instance, if you merge the M2V and AIFF or M2V and AC3 data into an MOV file container, then QT X will refuse to open the file. It also doesn't like muxed MPEG-2 content in VOB file containers.

    Here is the weird thing. When I playback a 30sec file that I create with the same preset it plays fine. When I try to open the files i create that are 2 frames they either come up black with a weird thing on the interface that looks like a 3/4 circle with an arrow pointing to the left and a 30 in the center (which what the devil is that) or it says the file cannot be opened.

     

    So I am at a total loss since I never had this problem on my old mac running 10.6.7 and QT 10.0

    Only a guess on my part, but it could be that the newer QT X player is programmed to consider these 2-frame files as incomplete since they contain less than one complete GOP (group of pictures) frame set which would also explain why the longer clips play correctly.
