It will not play saved videos from camcorder and it does not let me uninstall it. I get a fatal error message.
Remove all its components manually, and delete its entry in the add or remove programs in control panel.
QuickTime does not have support for a wide variety of video formats. For this purpose, you need to install additional codecs so that QuickTime can open the files from your video camcorder. Combined Community Codec Pack is the right codec pack that needs to be installed so you can play your files.
