Well that worked thanks Thom - now I just gotta figure out where they came from (as I said - closed network and I know those files weren't on any other computer on the network) and how to keep them from comming back again 
Thanks again Thom!

Thanks again Thom!

I was hoping I could just start TV and setup a manual record (I wanna record the Simpsons tonight since I have to go out) so I click TV from the list - it loads MythTV but I keep getting a message that all my tuners are in use when I select TV
