Most all of the new gear that has HDMI has HDCP
All of the AVRs with an HDMI repeater chip set include this..
Having it work rite is the challenge, checkout
www.digital-cp.com and you will find many brands do
not submit their products..
The other crucial point is that many source products with an HDMI transmitter also are not certified for HDMI/HDCP and compatibility with AVRs with an HDMI repeater..
Thats why many HDMI handshake compatibility problems are reported..
A few of the suspects are the Apple TV, Samsung Blu-ray players, Motorola STBs, Direct TV Sat tuners..
Primary reason they don't pursue the HDMI/HDCP certifications is to save time (ship sooner) and the significant $ expense ($15K-25K per submitted product)..
Just my $0.01..
