I'm having a problem with the 32bit media center on vista. It starts up so it goes onto the menu screen. I can use all the options(music, pictures etc) except for the TV+Movies section.
If i select live TV, recorded etc it just crashes.

I know my TV tuner is working because the software that came with the tuner works fine. Its just a issue with Media Center. Really stuck for a solution here, tried to google it but had no luck.
