Apparently, "dshow://" is not a valid media URL. What makes you think it is? It looks rather short.

Not sure. How do "dshow:" URLs normally look like?

I did a considerable amount of web searching and I couldn't find any pages at all which mentioned the concept of "dshow URL", let alone any examples of such a thing.

So then I searched the web for the error message and got something which claims to explain it: VLC is unable to open the mrl. (Searching for error messages on the web often produces a page -- or many pages -- describing the error. It's a useful problem-solving technique.)
