Solution for crashing players after Windows 10 update KB4013429

Monday March 20th 2017

This Windows update contains a new version of the file CompPkgSup.dll which has a bug that can cause applications to crash. It only happens when an application uses the Microsoft DTV-DVD Video Decoder or Audio Decoder on systems where MPEG-2 is activated in that decoder. That is either when you installed the DVD Player app from Microsoft, or if you upgraded from Windows 7.

Edit: Microsoft has fixed this problem in a new update KB4015438 (released on March 20th).

Workaround #1 (for MPC-HC only):
MPC-HC options > External Filters > Block both Microsoft DTV-DVD Video Decoder and Microsoft DTV-DVD Video Decoder

Workaround #2:
Codec Tweak Tool > MS Codec Tweaks > Disable Microsoft DTV-DVD Audio and Video Decoders
(Note: this may break video playback in certain apps, read the help for more details)

Workaround #3:
Download CompPkgSup Fixer (528 KB). This is a little tool that we made that replaces CompPkgSup.dll with an older version of the DLL that doesn't cause crashes.

Secure QuickTime installation tutorial

Monday September 5th 2016

As you may have heard, QuickTime has some security vulnerabilities, and there have been recommendations to uninstall it, since Apple is no longer updating it. Unfortunately, there are a lot of professional programs that need QuickTime. For example Adobe After Effects, GoPro Studio, and Sony Vegas. We have written a tutorial that shows you how to install only the essential components, and skip the insecure ones (such as the web browser plugin).
