Oracle Enterprise Linux is not a clone of RHEL anymore than Ubuntu is a clone of Debian. It's more like a fork but with several additional packages and changes for clustering that RH doesn't have. That pretty much makes it their own, no matter how you spin it. Besides RH will be de-listed when they are bought in the near future. :)

My HDTV also has a DVI connection. Attaching a HDMI->DVI cable seems to work fine though I don't get the audio. Which is no problem since that runs to tuner. As far as HDCP, that's working since my cable box whines when the TV isn't on first to negotiate the connection.
