Just watched my first movie (Airport 1970) on the now setup HTPC thingy using the WDTV Live streaming media player which sits in the home entertainment system (connected via USB to 4TB harddisk).
That sure was a lot of work, but now I have about 600 movies each with .xml and .nfo files for movies metadata/details (plus a thumbGen software metadata file), various images for cover art/poster, background fanart, moviesheet (fanart with embedded/overlaid movie info/details). So these movies are ready for use by both XBMC and also WDTV Live. I chose country of origin poster images to be the cover art for each movie (unless they were really hideous like some USA posters I used another country like Italian).
Here is a screen grab of the movies carousel in one of the movie folders:
I am using the default theme with the WD TV Live box which has its limitations such as the rating (star icons) system not working as it doesnt align to the IMDB ratings.
I embedded the IMDB rating into the end of the description field
followed by some of my own made up codes such as f:(foreign language), b:(black and white), c:(separate audio commentary track), plus others for levels of sex and violence, an alternate english audio dub for foreign language films, cinavia protection, animation. There is also a video technical quality scale I added: q2 (almost unwatchable),q3,q4 (dvd),q5,q6 (bluray). These codes tell me quickly a lot of info about the film.
