Vista - Capture Frame From Video File

Hi All,

I have a working .NET solution for capturing frames to an image from a video
file using DirectX.Video and dynamically disabling hardware acceleration (so
that an image is captured not a pointer).

This works on my old laptop running Windows XP Pro. I've tried to run this
on Vista. When the Video class is instantiated with the hardware
acceleration disabled, the application is terminated.

Faulting application bla-de-bla.vshost.exe, version 9.0.30729.1, time stamp
0x488f1c9b, faulting module unknown, version 0.0.0.0, time stamp 0x00000000,
exception code 0xc0000005, fault offset 0x0cdfd370, process id 0x1da8,
application start time 0x01c99609d2e45060.

Any ideas?
