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.

I have never installed the DIVX player. I am more fmiliar with it as a library item, not an application. In other words, something another application such as Quicktime uses as a resource to play files with DIVX codecs.


Did you check if there is an uninstaller in the installer package? If there is then that is the best way to uninstall it. If there isn't then it is likely there are multiple components in different folders on your computer. You can try using Spotlight to remove DIVX components. It's an easy method but not always 100% effective.


It is very unlikely the DIVX installation corrupted Quicktime player directly, but it may have told the computer to use an incompatible DIVX component every time you try to play a certain kind of file.


Try playing some other kind of file such as a music file with Quicktime Player. If that is broken then you really may need to reinstall Quicktime. We would need to know more about which operating system version you use.

I use an older system version (10.4) and I am not as conversant with how the newer Quicktime works. Spotlight for me is at the far right of the menu bar with a little magnifying glass. You may need to re-install Quicktime but I don't know how to do that on more recent systems. It could also be that permissions got messed up by the DIVX installation. You repair those with Disk Utility but I again don't see that recommended as a remedy as much as I used to for older application issues.

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:
