Now the output is in xmltv format. I don't think you can import that directly into Media Centre - never used that. I think there is another step using another app.... Read through this thread to find out.
As for whether Media Centre is the best program for Tv..... That's a whole new thread!
All I will say is that I use MediaPortal (through thick and quite a bit of thin). If you aren't into fiddling with installs etc. then Media Centre is probably the best thing.
EDIT: Couldn't resist reading back up the thread.... Someone mentions this as a tool to convert the file into something for Media Centre.... This tool was mentioned on reven's forums often. http://code.google.com/p/xmltv2mxf/
There's also talk of a thing called Big Screen EPG.
Do bear in mind that I might not know what I'm talking about wrt Media Centre.
