C00D7176 Media Player Error (c00d11b1)

Hi

I've just got a new laptop with Vista Home Basic, and I'm trying to play
some WMV videos that I purchased online. When I copied them from my old PC
and open them, it asks for my login to verify the licence, and when I do
it'll only play one out of the 3 videos that I have.

It's been giving me the c00d11b1 error code with C00D7176 as the basis for
calling that error code. The only difference that I can imagine seems to be
that the ones that won't play are using the Windows Media Video 9 Screen
codec as opposed to the Windows Media Video 9 codec.

By the way this video will play on my new PC once I've verified the licence
if I was to use Winamp, but without the video. This makes me thing that it
may be a codec problem. Is there a way to download this Windows Media Video 9
Screen codec if this is the case?

Thanks in advance,

JP
