Can't open files in quicktime player?

Save the file and open it from within Quicktime. Sometimes files are simply not recognozed by the creating program. You may have another file (like Windows Media) set up to read quicktime files. That'll create trouble.

I've been getting the same problem too using QuickTime Pro to convert .avi or .mov files to .mp4.  I've found it's really hit or miss with the conversion.  If one file doesn't convert,  I have to go find another that will convert.  Sorry if that's not much help, but I'm glad to know I'm not the only one!  haha

Open moviemaker from start menu\n\nGo\n\nfile>import into collections.\n\nA popup window will appear. Inside the window, navigate to where you have stored them. There's a list box in this window where caption says, " Files of type : " Click on the dropdown menu to select  " all files ( *.*) "\n\n------------\n\nAre you sure they are in right formats? Real and quick time formats are not compatible with moviemaker.

One of two things could be going on:\n\nYou either don't have the software to view multi-media files (like flash or quicktime)\n\nor\n\nYou have set your permissions to not allow active-x content in your browser.\n\nCheck to see if you have Flash Player installed on your computer, and Java.  If yes, then change your security settings under tools in your browser.

You can't, actually.\n\n"If you came here wondering how to make Firefox use the Windows Media Player plugin play a specific file type instead of Quicktime, then you should know that the WMP plugin is hard-coded to only play the proprietary Microsoft formats (.asf, .asx, .wm, .wma, .wax, .wmv, and .wvx), and Windows Media Player provides no provision for changing this."\n\nhttp://forums.mozillazine.org/viewtopic.php?t=206213

To resolve the problem, in Windows Media Player 10, do the following:\nClick Library.\nRight-click the file, and then click Error Details.\nIn the error message dialog box, click Web Help.\nAt the bottom of the Web Help topic, click the link to search for the codec, and then follow the steps on the screen to try locating the codec.

In Windows Explorer (or My Computer) find the file and right click on it.  Choose Open. When the window pops up, choose select program from list and click OK.  (If for some reasonyou don't get this window when you click open, then left click the file ONCE to highlight it, hold down the shift key and while it's held down right click the file.  You'll get an options menu and you can select Open With or Open - if Open with is there, choose that and you'll get the list of programs.)  From the list of programs, select whatever you usually open it with (Windows Media Player it sounds like).  Check the checkbox that says Always Use the Selected Program to Open.....blah blah  Then click OK.  It should open in WMP like it used to!

I think that you need to play the file in a more encompassing software, such as realplayer or windows media, both of which are free.\nwww.real.com

Windows Movie Maker can't (and won't) ever import QuickTime. The reason for this is that Windows Media files (wmv) are Microsoft's proprietary format, and QuickTime is Apples proprietary format.\n\nSo what you need to do is convert your QuickTime video into something that Windows Movie Maker can read. The best option is probably MPEG-4.\n\nNot surprisingly, the best way to convert QuickTime movies to MPEG-4 is QuickTime Pro (http://www.apple.com/quicktime/pro/win.html)\n\nIt costs around $30, and lets you save QuickTime files into a number of formats, including MPEG-4. Save your QuickTime file into MPEG-4, then you can open the exported MPEG-4 file in Windows Movie Maker. Once in Windows Movie Maker, you can edit and tweak it all you like, and even save it in WMV format.

First, check to see if you have the latest version of Quicktime. I had a similar issue. I uninstalled Quicktime, then installed the latest version, and that worked for me.\n\nAlso, if you are using Mozilla Firefox browser, you may need an addition plug-in. If this is the case, you should get a little bar at the top of your screen that says "additional plug-ins needed" and will give you steps to get the plug-in.

I have the EXACT SAME PROBLEM. I have the same problem when I try to load a clip. People have told me to download Movie Maker again, but I can't make it work properly. If you can, try that.

You can either change the file associations (what they call MIME Type Assignments).  However, I would just re-install Media Player.  It will take over agin and its much easier.
