ah. that makes more sense. Weird. I had heard about XBMC having scraping errors, but I haven't had that problem myself. keep me posted. If there is anything I can do to help, let me know.
I don't think WMP will help, because it should all be happening within xbmc's internal database. I don't think movies get tagged the same way as music files. If you are able to browse videos in library mode, with titles, covers, descriptions etc. then it should be working... If you want to VNC I would be happy to take a look at your machine with you and try to figure it out.
As for you accent, if you have one, then I recommend doing a little windows Speech training session. It can help a lot, and only takes about 5 minutes. I happen to have a very "vanilla" north american accent, and although I have been told that I sound Canadian, the voice recognition engines don't seem to mind it, and I get good results without training it. Even so, if I want to do open recognition where I can say anything, as for web searches or to do dictation, then training helps.
