From what I have read, HBO's HDCP issues on the ViP Duo receivers only show up when TV1 is on HDMI. As long as the TV1 is HDCP capable, I believe that the only way around the HDCP issue on TV2 is to have TV1 on as well as TV2. If TV1 is not HDCP capable through HDMI, then the only way around the HDCP issues is to use component cables, at which point TV2 will no longer have HDCP issues.
This is exactly correct. I have been trying to inform people of this for almost 2 years. Would you believe that 2 years ago everyone thought I was nuts, they even sent a tech out to replace my box. Incredible that an appropriate software fix has not been implemented, but oh well as I said before I have given up on HDMI to avoid the hassle. PS this is not just HBO, any HDCP coded programming will be the same way such as On Demand items. I know there will be people who say they have no problem and the reason is simple, your TV1 connected with HDMI still completes the "Handshake" when powered off. Some tv's do, a lot do not which is why everything works when the tv is powered on and does not work when powered off. Anyway, just some information for everyone.
