My HDTV is located in a room where there isn't any internet connection nearby; so when I want to update my PS3 or download from the store I need to move my PS3 to a room with a regular SD TV, however the PS3 doesn't autodetect that I changed from a HDMI cable to an A/V cable. I've tried changing it in the setup, but when I select A/V cable I get stuck on a screen where I have to select which resolutions my TV supports, but then I can't enter anything, I can only go back, which reverts to HDMI..........anyone know what the deal is?
