Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Preferences/com.apple.quicktimeplayer.plist. Move the .plist to your desktop.
Open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.
You might need to redo the View settings after an update.

HT3775 I have an .avi file Quicktime is refusing to play, yet the information says Quicktime does play .avi files. Does anyone know what the problem is?

AVI is a legacy file container originated by Microsoft back in 1992 and which has not been officially supported for more than a decade. Like the container, many of the codecs commonly used to create AVI content are also "legacy" compression formats most often supported on PC/Windows platforms. In fact, some codecs have never been transcoded for Mac use. Of those that have, many never made the transition to Mac OS X or the transition to Intel-based platforms. Those codecs that are still supported on the Mac can normally be found in the avi to quicktime converter available as an online download. While some common AVI compression formats may be supported by the QT X Player app, QT 7 currently provides a more compatible AVI playback environment for most "legacy" compression formats. If the codec(s) used in your AVI files are not supported by the avi to quicktime converter for QT use, you can try the VLC media player which may still support more esoteric compression formats. If VLC does not support the files, the normal approach is to discover which specific audio and/or video codecs were used to create the file and perform an Internet search to see if a compatible Mac component is available for download.

Why won't FireFox 4 play mp3 files that have been created since the FF update? It will play mp3 files created prior to the FF update. All of the mp3 files have been created in the same manner, as bounces from Logic Pro 9. Thank you.

Hi David,
Thank you for your detailed question. It sounds like the real issue is pdf files. Are there any antivirus/firewalls that might be blocking this specific file type? or are there any preferences in your control panel that might be blocking this?
Do you have any stored preferences for PDF files in Firefox?

QuickTime X plays avi files ???

Hi,
I just upgraded to Snow Leopard, and for no reason, I tried to play an avi file with QT... and it played !
I thought that QuickTime didn't play avi files...
I installed no codecs anything, there's hardly a non-apple software on my mac ...

I thought that QuickTime didn't play avi files
That AVI file contained audio and video playable with a bundled codec. Some do; others require a tool such as Perian, and still others can't be played in Mac OS X. AVI is a container, not a format, and no single codec or component will guarantee that any computer, Mac or PC, can play every AVI.

Why won't Quicktime Player open a .mov VR file ?

(I'm on a new MBP, with Yosemite 10.10.2, QT Player v.10.4)
Nothing opens except the app when I double click on a .mov file, the playback controls don't even come up.
This does not happen on all .mov files, but several VR files which were outputted to Quicktime.

I think I figured it out:
The new osx QT (with Mavericks and Yosemiteseems to be the issue (see http://osxdaily.com/2014/07/20/run-quicktime-player-7-in-mac-os-x/)
I downloaded the older Quicktime Player 7 and the files work perfectly

Why doesn't Quicktime 10 play 3GP Files?

I recently got a new MacBook Pro and the Quicktime player won't play 3GP files. I prefer playing certain audio files via Quicktime and now this is a big hassle. My previous Mac played them without issue and I'm wondering why the compatibility was removed from the new Quicktime? Is there a 3GP codec for QT 10 or is my only option installing Quicktime 7?
Thanks,
-Adam

You can only use QuickTime Player 7 to play that 12 year old format.

Quicktime not playing .avi file!

I have been trying to figure out why it doesn't play for a day now. The thing is, it only doesn't play this .avi file, others I have can play it. It says it needs another component to play it and directs me to the extra quicktime downloads page, but I don't know which one I need. I tried downloading the XviD component, but now it says "Movie cannot be opened. Mac OS Error -1." I need help!

I just solved this issue on my machine. Something in the Perian bundle also conflicts with Intel core MacBooks. I finally resolved the issue and avoided the white screen by removing ALL 3rd party QT plugins (including Perian) and restarted. I was then able to view the AVI files and avoid the white screen. When I added back Perian, I could again not see the files. So, the solve is remove ALL QT 3rd party plugins. I suppose you can add Perian back after you have used the files you require, but be aware there is still an Intel conflict within Perian for certain AVI files.

Why won't iDVD burn my .avi files... it used to?

i have files ending in .avi that i want to burn to a DVD, in order to watch them on television.
i throw them into the iDVD and the preview shows nothing but a blank screen.
iDVD used to burn my .avi files.
i have converted them to .mp4 / .mpg / .mov... but nothing seems to work.
sometimes, throwing a .mp4 file into iDVD nothing happens at all, or it will say unsupported / unrecognized file.
the only time it did work was when i used a program to convert a file to .mp4, but now it has a huge watermark across the picture.
why all of a sudden does it not work?

Hi
If QuickTime-player opens Your .avi files then start Inspector (cmd+I) and read
Video Format/Codec: nnnnnnnnnnn
What does it read ?
What did an old .avi file that worked - read ?

Using Quicktime to Play AVI files

My Canon PowerShot creates AVI movie files. These play fine on my mac through iPhoto. I then drag them to my desktop so that I can attach them to an email. When I email them to family who also have macs (who are on 10.4.2) with QuickTime, they are unable to to open them. When I email them to my Windows PC it says that the file is not a movie file and cannot be opened with QuickTime. I've tried importing it to imovie and saved it as a .mov but that did not help.
How is one supposed to play an AVI file outside of iphoto?
These are some of the errors I get:
QuickTime cannot open the file: "MVI_1670.MOV"
it is not a file that QuickTime understands (-2048)
Or Error -32

hi Nat,
I got the avi file in my email. this is what happened to me:
I waited for a couple of minutes for it to download then double clicked the icon file for the avi in the email and nothing happened.
I then hit the "save" button to save to the desktop. I did this twice and nothing was saved to the desktop.
I then tried to drag the file from the email body to my desktop and got the spinning ball. Mail turned unresponsive and I finally had to force quit it.
I went to .mac webmail and opened your mail there. I clicked to download the avi from the webmail. took a couple of seconds and then it opened in quicktime just fine. You have an adorable doggie!!
Next I went back and opened Mail.app again. This time I went to Window>Activity viewer to see what was happening.
In Activity Viewer I see that it is stuck on "downloading attachment" and "caching attachments"
It's been over 10 minutes and it still has those two things showing in the Activity Viewer.
Ok, 14 minutes went by and now the AVI file is finally showing up in my email message and I can play the file within the message.
I don't know but maybe they didn't give the file enough time to download to their computer. It certainly gave me problems until it was all downloaded.
I have the latest OS and the latest Quicktime and it plays fine on my computer.

Quicktime delays playing AVI files

Since upgrading to 7.2 it now takes around 30-60 seconds to open an AVI file in Quicktime. I use Flip for Mac and this used to work fine, opening an avi file straight away.
A friend is having the same issue.
I can open the AVI file fine in VLC Media Player.
Your comments please....

Try it on your stubborn AVI's.

HT204382 why won't QuickTime player work?

I cannot download video's sent to me email through quicktime player

QuickTime does not natively support Windows Media format. So you need to get the plugin from Flip4Mac that does support WMV. Note that the free version only provides playback. If you want to import WMV files for editing or export in WMV, you'll need to purchase one of the paid versions of the Flip4Mac codecs. Another option for playback of some Windows Media content is VLC Media Player.

HT3775 Why can Quick Tim player play AVI format from cameo video camera?

Here is the message I get when I try to open the file.
The file could not be open, a required Codec isn't avaible.

The only problem with that link is that it is a bit of an infomercial. It is good for solutions #1 and #2, but solution #3 is somebody trying to sell your something. Install Perian (free). Install MPEGStreamclip (free). Convert for free. I am sure there are many other free converters.

Why won't Flash Player, play?

The Flash player installs fine, so it says, and then when the window comes up to show it is working, no video to verify it is working. Now what? I have taken the security settings off and deleted all the past history, deleted old versions of Player. Still will not let me access sites that say I have to upgrade. I see a lot of problems with this flash player 10 but no real solutions. I am running IE8 with Vista. Any help will be muchly appreciated.

Hi there.
I am new to this forum and signed up just so I could include my own frustrations with this very same problem!
I am located in Canada and prefer to watch streaming video over regular TV. For some reason, the CBC player stopped working for me when I upgraded my Flash Player. I do not recall which version of Adobe Flash I had installed when this problem started to occur but I know it wasn't the most current version (10,3,181,34) that I have now. But it definitely seemed to follow the Flash update.
I have Flash version 10,3,181,34 now. I have updated to Firefox 5. Active X, javascript, etc is all enabled. I have walked through all of Adobe's troubleshooting steps. I have tried disabling my anti-virus. I tried re-installing all of my browsers, plug-ins etc. yet the problem still persists. And I am in the exact same boat as the poster in that I can still watch Flash player streaming content from all other websites but not from CBC.ca!
So I was happy to see someone made a post about it because it is incredibly frustrating and CBC.ca doesn't respond to inquiries/troubleshooting complaints directly.
I'm pretty technologically adapt as I am a system administrator and lon-time IT professional. Should I ever get this problem resolved, I will be sure to post here, otherwise I will pop back now and again and see if anyone else has come up with a solution.
Cheers and thanks again to the poster for posting this!

Quicktime 7 won't play avi files

can someone please tell me why this is?
It's only stopped playing them since its been upgraded
i just get a white screen and the message that there might be a missing component?
Sorry if this question has already been posted!
Please HELP
iBook G4 Mac OS X (10.4.8)

If QuickTime is set to play avi files in System Preferences, then the avi might not be one that QuickTime can play. There are several proprietary avi codecs. You might try VLC player or some other player that can play all the different kinds of avi codecs.
