mark category as 'movie'

I'm still a happy user of Windows Media Center, and for my EPG-data I use Web Grab + in conjunction with the horizon.tv (ziggo)-website.
Problem is, that the categories that Ziggo uses most of the time don't differentiate between movies and series. For example 'The Chronicles of Riddick' is only categorised as 'Sci fi' and not as 'movie'. Certain sci fi-series ('Dr. Who') have exactly the same category. 

Is it possible that using mdb, when IMDB finds a match, <category>Movie</category> can be inserted in the EPG data?
