Barry,

Movie and TV shows are not that hard in XBMC and you don't need external tools. I've got a 95% succesrate and almost all others can be corrected from the interface. Just make sure you use the database mode.

Save your movies in a subfolder like this: 2 Fast 2 Furious (2003)
And your TV series like this: Grey's Anatomy\Grey's Anatomy S06E11.WMV

Make sure you use the exact name from imdb with year and the exact seriename from thetvdb. If a movie still gives the wrong info select update info and select another movie then the top one.

If you have trouble getting the database mode send me an email and I'll (write and) send another guide. I didn't have time for the postscript for clownbd and probably won't in the next 6 weeks, we've bought a house.
