I'm trying to hook up a slingbox (SD) at my sister's house. She has an HR24, and a few H25's. I need to hook up to one of the H25's. However, before I go out there, some questions have come up. Her H25's are connected to the TV's via HDMI. I know that the H25's have composite out (which is what I need.) Can the H25 output both HDMI and SD at the same time? Also, the best H25 to use is in the bathroom, but I'm also about to install the RF kit on that one. Can the H25 work on both RF (DirecTV) and IR (Slingbox) at the same time? Thanks. Nick.
