Why can I not open a attachment that has the suffix .mpe?

A friend and I both received an email with an attachment that has the suffix .mpe.  When I try to open it I get a message that Quicktime can not open the file- that it is in a format that Quicktime doesn't understand.  I wrote both the friend and the sender and they say their machines open the attachment.  If I drag the attachment to my desktop and change the suffix to .mpeg I can open the file.
I don't know if it is relevant, but they are both using mountain lion and I am using snow leopard.
Is there a logical explanation for my inability to open the .mpe attachment?
Thanks
Dave

I am hesitant to believe that the reason they can open the file and I can't is because they are running mountain lion and I am not.  It would seem to me that Quicktime is Quicktime no matter which operating system one is using, or...?
Incorrect. It's not so much the system itself, but rather the QT structure embedded in the OS together with the different player apps. They are probably running QT X v10.2 (603.6) while you are likely using QT X v10.0 (131) and there have been some major changes between the two during the interim. E.g., try playing "muxed" MPEG-2/AC3 content to see the difference in audio support between OS v10.6.8/QT X v10.0 and OS v10.8.2/QT X v10.2. Another major change was the disabling of legacy codecs—they're probably still enabled on your system but disabled by default on their systems unless they re-enabled them. To say the least, QT is constantly changing and that is why so many people are here trying to find out why something works or doesn't work in one instance but is totally backwards following a certain OS upgrade or app/security update.

  • Why can I not open some attached emailed pdf files?

    PLEASE HELP ME! I HAVE TO OPEN THESE FILES MY BUSINESS DEPENDS ON IT! why can I not open some attached pdf files and others are ok?

    PDF files are extremely reliable. You may have a software issue. I have the problem on 2 identical systems with the exact same specs. The problem occurs at the same exact interval. It may be a windows update. We have had to re-install software form the DVD in each instance. This fixes it for awhile and then it recoccurs. Adobe acts as if they have never heard of the problem...imagine that. I'm the only one with th problem.
    This is happens with CS6 volume lic product.
    If you dont own Adobe product it will be even more difficult to find and answer as the reader is used my so many people.
    We know we have the problem again when we double click opn a PDF and nothing happens. SOme have reported that reloading does not fix the problem.
    Wish I could help you. I am looking for answers to this issue right now and phone support is a 30 minute wait.
    Very frustrating.

  • Why can I not open a new tab in the new Firefox? (via the + sign or Ctrl T)

    In the new interface on Firefox (which started for me today ... May 2 ...), I cannot open a new tab via the "+" sign along the top or by using Ctrl + T. If I want more than one thing open at the same time, I need to open a "New Window", which doesn't make much sense. I don't necessarily want a bunch of windows but may need a few tabs open at the same time.

    Hi bmail, I am attaching an illustration of cor-el's suggestion showing what it does since I wasn't aware of that before.

  • Why can I not open a new tab using the New Tab button, going to File and clicking on New Tab or by pressing ctrl + T?

    I am able to right click on a link and choose "Open in a New Tab."

    This issue can be caused by the Ask<i></i>.com toolbar (Tools > Add-ons > Extensions)

    why can't i open an attached document (most often pps) with firefox when i can with internet explorer?

    Perhaps if you change your setting here:
    orange Firefox button ''or'' Tools menu > Options > Applications tab
    In the search box, type '''power''' and then pause until the list is filtered. If you have these, try changing the action to "Always Ask":
    Microsoft PowerPoint Presentation<br>
    Microsoft PowerPoint Slide Show
    It's possible that if you don't have Microsoft Office installed, you might not have those listed.

  • Why can I not open PDF-files in InDesign CS4?

    Hi,
    Well then, as I wrote in the headline... Why can I not open PDF-files?
    I get a notification that says that either the file is already open (which it's not) or it is missing a plug-in thingy for this kind of file.
    So, how do I know which plug-in thing I should chose from Adobe which will solve my problem?
    Could it be enough just to update the program? I tried with 6.0.6. upgrade but it wouldn't even open up. I'm not so good at this type of computerproblems (choosing upgrades, plug-in etc.). The program is not upgraded for a long time, unless it do it automatically, but I think we've chosen it not to....
    Please help!

    You need to have Application manager installed.

  • Why can't I open a PDF that I emailed to my self

    Why can't I open a PDF that I emailed to my self

    OK. You mean that it has fillable form fields. Those will not open in the mail app or in iBooks.
    Download Adobe Reader in the App Store. It is free. Then go back to the mail app, tap on the PDF file to get the Open In window to pop up. When the Open In window pops up, select Adobe Reader. The PDF will open in Adobe Reader and be saved in there. You should be able to fill out the fields in the Adobe Reader app and then you can email it from there if needed.
