I just bought a vp6320 and had to call HP support for a technical issue. I was unable to use a HDMI to DVI cable to connect my SA HD cable box to the projector. I kept getting a HDCP error and I know it is not the cable box. I work for the cable company and I am very familliar with the 8300HD. After fighting with HP they tell me their projector does not support a HDMI to DVI cable. Has any heard of this? I thought this is proven technology? Why would HP advertise it supports HDCP when it dosent.
