COM Surrogate has stopped working

We are running Windows Vista RC2(Build 5744) on a:
AMD Athlon 64 3400+ 2.4 GHz
1,5 GB RAM
ATi Radeon 9800 pro 128 MB
2 x 250 GB Western Digital Sata Drives
32-bit Windows Vista

Everytime when we open a folder that contains video-formats, such as MPG or
AVI we recieve the following error message:

COM Surrogate has stopped working

A problem caused the program to stop working correctly. Windows will close
the program and notify you if a solutions is available.

And we can click Close Program, but then nothing happends and the error
message appears again. Until we close the folder then the message dissapears.

*Note: Everything works fine if we open the folder but the message is
annoying.
