I changed my Windows Media Center "Recorded TV" folder to a different partition. After I recorded a program, I was able to view it on my PC and also "PLAY TO" my TV. I lost the ability to see those files from my SONY Bravia. I can still access my PC as a server and can view other video files, but the "Recorded TV" folder shows as empty. I switched back to my original partition and still no luck.
