Since "upgrading" to Lion my MacBook Pro won't play .mov or .wmv files, all I get is a black screen and the audio.  It's so frustrating!!    

 

I've read many other posts all along the same lines and wherever possible I've tried to follow the advice which has been given but nothing works.    I've updated all the drivers I can and I've even reinstalled Lion, nothing makes a difference.   

 

I'm not really looking for any more advice, all I want is someone from Apple to read these posts, realise there is problem and get working on a fix or update.   

 

I had no problems when running Snow Leopard and it would seem, looking at everyone else's problems, that the common issue is Lion.   Seriously, this is one area where Lion is a backwards step.   It should just work (like most things from Apple), but it doesn't.

 

Personally I believe there is a problem with Lion but from what I've found out from speaking to friends with other Apple kit, this might be a random issue only affecting some people as some have said they've had no problems while others have had the same issues as me.    One guy reinstalled Lion and it resolved the issue for him, I've not been as lucky.  

As I say, I'm not really looking for more advice, simply some sort of update from Apple to fix it.   PLEASE!!!

    Download and install:

     

    Flip4Mac WMV Player from  http://www.telestream.net/flip4mac-wmv/overview.htm  (Windows Media Player for the Mac is no longer supported, even by Microsoft)

     

    Perian from  http://perian.org/

     

    You should read this support page  http://perian.org/#support   in case you need to delete older codecs.  In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them), particularly any DivX extension to Safari. However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from  http://www.divx.com/en/software/mac/player

    This is a peer-to-peer user forum. Perhaps you would see more action if you and others would file a formal "Bug" report with Apple QuickTime technical people rather than repeatedly reporting a possible problematic problem which may or may not affect others on a random basis. QUICKTIME PRODUCT FEEDBACK

     

    Since you aren't seeking further advice here is what I have observed. Not being a regular WMV file user, I had to create my own sample file to test—a WMV 9 file containing WMV3 compressed video and WMA2 compressed audio. Since I normally use QT 7 as my primary media player, I also stored the WMV data in its partially decompressed form in an MOV file container to avoid pre-playback delays in "classic" player routines and also provide a secondary playback test of MOV wrapped content. These files play as follows using the Flip4Mac component/player support and uncoded URL uploads:

     

    QT 7.6.6 "Open File" - both files play correctly.

    QT 7.6.6 "Open URL" - both files play correctly.

     

    QT X.1 "Open File" - WMV file plays correctly. MOV file plays video without audio.

    QT X.1 "Open Location" - WMV file appears to open but plays with "black" screen and no audio. MOV file plays video without audio.

     

    VLC "Open File" - WMV plays correctly. MOV file doesn't open,

    VLC "Open URL" - WMV file plays correctly. MOV file appears to open but nothing plays.

     

    MPEG Streamclip "Open File" - both files play correctly.

    MPEG Streamclip "Open URL" - both files play correctly.

     

    GarageBand - WMV file will not import but MOV file does.

     

    iTunes - WMV file will not import. MOV file container is accepted but as soon as iTuness sees the compression formats, it aborts import.

     

    Safari - WMV file URL auto-downloads and playes in the QT X.1 Player. The MOV file URL opens and plays in Safari.

     

    As you can see from these results the files do play but are subject to many different constrints based on old/new video technology support, independent QT subsets and/or container trapping constraints. In short, individual user results will depend on presence/absence of component support, actual compression formats, file container, application being used, and how the application is being used. Unfortunately, most users here can't or won't provide the prerequisite information or a sample file for independent examination. This makes it next to impossible to give advice in these matters or categorize the specific nature of the problem.

    Hello Jon,

    Thank you so much for your help and very detailed investigation. I'm not an advanced user of the mac, and really lost after the Lion upgrade. Your both sample files loaded very quick and played well, with the audio, no problem. I'm lost even more... how to fix it? On your advice, I'll file a Quick time product feedback. Hopefully there would be an official help. Jon, If I may ask for your professional opinion, what can I do to fix the problem.

    Thank you for your help,

    Anjella

    Jon, If I may ask for your professional opinion, what can I do to fix the problem.

    As these problems can be very complicated depending on specific user system configurations, user work flows, and the like, it often is not possible to provide a general "fix" that will work in all cases. If you are a member of a local User Group, my advice would be to get some one-on-one time with a knowledgeable Video SIG member who can evaluate your system (hardware and software configuration) as a whole and eliminate the most obvious problems, With QT being virtually re-invented, I anticipate we will be seeing many such problems over this decade as support for "older" technogies is abanded for the "newer." Every new "fix" seems to bring other new and unexpected issues.

    HI,

     

    I upgraded to lion this morning ( nov 11, 2011 -- on 3 yr old MBP) and could not play any OLDER .mov (created more than 18 months ago).  Newer ones worked fine.

     

    Install of QT7 for Lion ( http://support.apple.com/kb/DL923 ) solved that --not sure if it is the same problem, or if ths work around will help you.

     

    good luck.
