I am considering switching from Dish to FIOS. I know that the DVR and guide are an issue but I may be able to get past that. I have 2 HDTV's. If I get an HD Multi Room DVR for the main tv and a HD STB (no dvr) for the second HD TV can I watch everything from the HD Multi Room DVR on the second HD TV in HD? Also if I change the second box to be a HD DVR can I still watch anything from the HD Multi Room DVR?
