Video player example - Pointing the category xml to a video?

Hi

Sorry if this has already been answered, can't find anyone else with a similar question when I searched.

I am currently putting together my Roku channel and hope to launch soon. Been basing the channel on the videoplayer example, as I've seen recommended by other users. I have my categories and XML files working, but I was wondering if it's possible to also play a video file from the category/home screen? So rather than go to another XML file for the category, some of the icons launch straight into a video instead?

Thanks for your help!
