I currently use an Optoma RD50 DLP RPTV as my primary display. This TV has no HDCP, making it difficult to upgrade to HD-DVD, Blu-Ray or any future HDCP-enabled source.

Is the DVI on the 970 a pass-through only? Does the 970 have an HDCP module built in?

If not, is there a relatively cheap solution to this situation short of replacing the tv? Any external modules?
