Note: my system had an InterVideo WinDVD player installed before installing the DMF5 trial, so MS MediaPlayer 10 was using the InterVideo video decoder for MPEG2 playback, without problems.
InterVideo AVControlSDK 6.00 was installed automatically by MovieFactory 5 during its setup (no choice to skip).
This broke MPEG2 playback of MS MediaPlayer on my system:
MediaPlayer now had an "unknown error" after playing an MPEG2 clip. Also, there was often a long delay at the end of playback before showing the clip as "stopped".
InterVideo AVControlSDK was installed in its own folder, but it had updated and overwrote many of the WinDVD files in C:\Program Files\InterVideo\Common\Bin
And these "AVControlSDK" versions don't work properly on my system with MP10.
Unfortunately the AVControlSDK installation was made to not show in "Add/Remove programs". So I added a "DisplayName" value to the "Uninstall" registry key A644254B-92F6-4970-8635-AB0775371E72.
This requires advanced know-how, not something the average user can do. But this allowed to correctly uninstall it via "Add/Remove programs".
I also uninstalled the InterVideo WinDVD player, because its files had been overwritten by the AVControlSDK from MF5.
Now MPEG2 clips played in MP10 again, without the "unknown error".
MP10 was now using the Ulead MPEG Video Decoder, by the way.
The InterVideo codecs were all gone.
After installing WinDVD, MP10 was using the InterVideo video decoder I had before installing MF5, and everything was still OK.
Any features of MF5 that require the AVControlSDK will not work because I've removed it. But I haven't found anything that needs it.
Summary: MF5 installation may break your MediaPlayer playback if you already had InterVideo software (WinDVD) installed.
