Issue resolved.

I finally got so sick of it tonight that I went and completely
reinstalled Vista. Problem sorted now, 4OD playing videos and not
bitching to be about my DRM. I think it came down to a hardware issue.
I had recently upgraded my processor and RAM and updated the BIOS for my
motherboard while I was at it.

Read that the DRM on Vista is linked to your hardware configuration so
the only solution I could see was to do a reinstall. A bit drastic but
I think my PC could have done with a good clean up.

Cheers anyway.
