I have been struggling all day with this same error as stated above; where Mac OS X using VLC does nothing when Play Downloaded Movie or Play Streaming Movie in DVArchive. If the path is incorrect; then I get an error in the Messages; but if the path is correct I get no messages; nothing that I can find in the console either. I tried to set the -debug flag in the Get Info; but that didn't give me any more information either. (I don't think it was working to give me more verbose output).
If I use the Quicktime Helper; it launches Quicktime; but doesn't launch the movie.
I am able to launch VLC and the movie from the terminal with the correct VLC path and the full downloaded movie path. I wanted to try the streaming; but I found where others talked about the need for DVArchive to proxy the httpfs for streaming; and I tried a bunch of combinations of the http proxying through the dva IP address; but couldn't get it to work (kept getting HTTP 400 Bad Request trying to send it into VLC).

All said and done... I am at a total lost as to why the VLC app does nothing when I try to play a movie from DVArchive.
I'm out of answers; I am applying a Mac OS X Software Update and going to restart--keeping my fingers cross.
I'm running a brand new (few weeks old) Mac Mini 10.8 (before the update).
