Quicktime 10.0 won't play any of my wmv videos - help please

I get a pop up that says I don't have quicktime installed. Can anybody help? Thx

I assume you normally use the Flip4mac QT plugin to open WMV file. It hasn't been updated so it will look for QT 7 and not find Quicktime Player 7.
The fix is easy:
Control+click on any WMV file. Then select "Get info" from the drop-down menu. Change the "Open with" setting by selecting "Quicktime Player." You may see two "quicktime Players" listed in the drop-down menu, select the one with the new "Q" symbol. That will be the QT 10 Player. Click on "Change All" and now they should all open with the QT 10 Player.
Some feature still won't work with Flip4Mac until it's updated.

  • Quicktime Player Pro won't play any movies?

    Ever since I restored my computer about a month ago, my Quicktime Player won't play any video formats correctly. .avi files don't play anymore, and mp4 files only play sound with the screen black. Then when I try to close the application, I get the pinwheel for a long time, thus making me force quit every time. How can I fix this so it can play movies correctly?
    (I'd also like to know how to get it to play .mka format movies as well)

    Courtney,
    There are a lot of possible CODECS used with .AVI file, not all of which are available for the QuickTime player.
    If you just want to play the AVI files use the free VLC media player found at http://www.videolan.org/vlc/

  • TS3961 Quicktime in Lion won't Play MPG/MPEG-2 format Video

    I have OS X Lion but quicktime still says "QuickTime Player can't open "M2U02230.MPG" because a required codec isn't available."  Does anyone know what codec is needed?  Apple says that Lion will play MPEG-2/MPG format and MPEG-2 Playback Component is no

    No, Quicktime does not natively play muxed formats.
    For that you need mpegStreamclip:
    http://www.apple.com/downloads/macosx/video/mpegstreamclip.html
    which is free, as well as the the Apple mpeg2 plugin :
    http://www.apple.com/quicktime/mpeg2/
    which is a mere $20.

  • Now my superdrive won't burn any DVDs. Can someone help please?

    Hi.
    I mentioned earlier in the 'won't burn dvd' topic that my Superdrive wouldn't burn DVD-Rs, saying there was a fault in the burning and the multiplexing.
    Now it's spitting out my DVD+Rs as well. As a film student at a college that likes DVD submissions, this is terribly inconvenient. The computer gets as far as encoding everything, then spits out the disc as the burning begins.
    I have tried completely re-loading my system, but still have a problem. Is anyone else having this problem and can they help me. Time is of the essence!
    Many thanks.
    PS. Check my post on 'won't burn dvds' for more info!

    Ok. As an addendum, I reset the PRAM and PMU. I also repaired disk permissions. I can burn DVD+R again at 2.4x speed. When burning, DVD-R, however, it spits out the disk and states (when I try to burn on its stated maximum speed of 2x): 'Unable to burn to "disk3" - The device failed to calibrate the laser power for this media..'
    I'm not sure what that implies beyond the obvious: is there some sort of power control issue I need to deal with on the system?

  • My quicktime player won't play any videos on my Mac X os. The video will start on quicktime then automatically start

    My quicktime player won't play any videos on my Mac X os. The video will start on quicktime then automatically start. I installed DiV X today and all this happened is there anyway to fix this?? I went through everything dragging the icon to the trash and deleting it from safari extentions.

    Download and install
    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  Note that Perian will be discontinued after the release of Mountain Lion:  http://reviews.cnet.com/8301-13727_7-57434082-263/perian-plug-in-for-quicktime-t o-be-discontinued/?tag=txt;title

  • Updated itunes and now it won't play any of my music, updated itunes and now it won't play any of my music

    i updated my itunes, and now it won't play any of my music. i tried deleting it and reinstalling itunes, but it still is doing the same thing: whenever i click on a song, it looks like it's going to play (and my last.fm thing starts scrobbling it) but it just doesn't play the song, ever. it sits there, with the play button played. i am so frustrated with itunes, and i have no idea how to resolve this.

    Michael,
    Thanks. I haven't mixed down the audio or checked the number of tracks in Prefs. Good points.
    As far as a mixdown goes, I'll definitely give it a try, though I wonder whether or not the tracks will be recognized during mix down recording - given that you can't hear either of those segments in playback. Just have to try.
    Re the preferred number of allowed tracks - I'll go check as soon as I send this off, but I'm not sure that applies in this case, since the two Channels containing the segments that are pinked out are not in additional tracks. I should have mentioned that other audio clips and segments on the same Channels in the SAME tracks ARE heard in playback. As are two additional track in the 2nd Sequence. It's only when the two sequences are joined that the pink tinted segments can't be heard. Within the sequence the same audio cuts playback as they should. Thanks again &
    Best regards,
    David

  • Ipod Nano won't play any songs downloaded from MySpace pages...

    My first generation Nano was initially sent back to Apple due to the battery losing it's charge to quickly. They sent me back what appears to be a replacement Nano and now this one won't play any songs downloaded from MySpace pages of bands, shared from friends (unprotected mp3 files) or otherwise downloaded from the internet.
    Whats unusual is that any songs imported from a CD to the Nano play fine as do any songs purchased from iTunes. I know Apple has stated that any files the user wishes to play on their iPods will play as long as the format is compatible. (All of these songs in question played on the original Nano and the problems started when they said they fixed it and sent it back (although it is missing the engraving which to me indicates they gave me a refurbished Nano). My Applecare runs out in mid-October so I need to figure out what is wrong. I sent it back a second time and they told me they couldn't recreate the problem so they just updated the software and sent it back.
    Someone suggested that some iPods have a part of the firmware activated (which Apple may have been testing) that prevents any non-ITunes store music or music no t off an original CD to fail to play.
    When attempting to play downloaded songs from sites like Purevolume and MySpace the iPod plays for a few seconds then shuts down and restarts itself, all of these songs worked fine before Apple took it in for service.
    Any suggestions?

    Hello,
    I have exactly the same problem. It`s so annoying.
    I did a little bit research on this discussion board and this problem seems to be known for quite a long time. It`s confusing me Apple is not able to fix that prob or give customers quick introduction to resolve the prob.
    I am currently on vacation in Florida and just bought the new iPod 30 Gig. I transfered already songs from my music cd. That worked fine.
    I bought 2 music video files, synced them with no error to the iPod, but it only shows me a black screen when I want to start the video on the iPod itself. itunes plays the files with no problem.
    Any ideas how to fix it??

  • I upgraded to the latest iTunes 10.2.2.12 and now it won't play any music. I can do everything else, except play music. I'm on Windows 7. Any ideas?

    i had this problem and finally figured it out. all that you need to do is go to your start menu and click on computer. select your main drive, (local drive) c usually. Next open the users file follow by your user name file, which is just like it sound it is a file labled as whatever your name is as you have it on your computer. Then you open up the AppData file. Next open the Roaming file. After that open the Apple Computer file followed by the iTunes file. Now you should see the folder labled iTunes Plug-ins folder. Now just Delete that folder. After that go to your iTunes and play your music.
    If for some reason you don't see the AppData file you need to go to the upper left of your screen on select organize. a drop down menu will appear and you need to select folder and searc options. a small folder options window will appear. in this window you need to select the view tab. you need to select the show hidden files, folders, and drives bubble. now hit apply and then ok. that will allow the AppData folder to be seen.

  • I have just updated my iTunes and it won't play any of my songs. What do I do?

    I have just updated my iTunes and it won't play any of my songs, It will say that it is but the time does not move along and the sound does not play. I have uninstalled and reinstalled it but it hasn't worked. What do I do?

    Hey B Noir!
    Changing the 3D worked for me!
    I am so glad that I ran across your post. I had been reading "solutions" to this problem all day, and most of them said to install/unistall/re-install itunes! No way! I knew there had to be an easier way, and you had it. Just a few clicks, and that was it.
    Thank you for your help!
    God bless.

  • .flv and .avi won't play any more.

    I had all the relevant codecs and was able to play .flv files in QuickTime and in VLC Player and also .avi files.
    I reformatted my MacBook Pro for unrelated reasons, and now since installing all the same codecs etc. I can't play .flv files and also I have .avi movies which play with no sound in QuickTime, whereas they used to before reformatting.
    I have installed:
    QuickTime Pro 7.5
    DivX
    XviD Codec 1.0
    VLC Player 0.8.6i Janus (Intel)
    Perian 1.1
    Does anyone know why suddenly there is no sounds for .avi in QuickTime and .flv won't play at all in QuickTime, VLC or the DivX Media Player whenever it used to work fine? I don't want to have to install more media players.
    Cheers.

    Same problem as Somhairie...
    But only .flv files won't play. More exactly I've lost the sound.
    despite what you say, Toronto..., I had the same codecs installed as described by Somhairie and it worked fine before I reinstalled all OSX.
    Some new ideas someone ?
    thank

    Thank you!

    Well, I hadn't rebooted after the 7.1.1 upgrade, but obviously I had to restart iTunes. After I rebooted my iBook iTunes worked... Maybe the 7.1.1 update should be marked with a must reboot?
