    Anyone successfully splitting the output from your HR20 to 2 HDMI TVs?

    If so, what splitter did you use? I've read all sorts of non-success...

    It's not just a weaker signal problem. The HDCP and HDMI resolution can only be negotiated with one TV, and the link to the second TV may then not work correctly.

    Good point. I was trying to keep the explanation simple :)

    It can still be done though, you just have to get a *more expensive* HDCP compatible splitter. Here's a little more info:

    Disclaimer: I've never tried this product or splitting an HDMI signal, just passing along what I've seen.

    The problem is that with HDMI being a bi-directional communication protocol both pieces of equipment need to "shake hands" before they communicate successfully with one another.

    A true HDMI splitter is actually more of a repeater. It has to decode and re-encode the signal to the two outputs and each of those outputs has to shake hands with the display devices.

    This cannot be reliably done with a Y-cable type solution. It may work on devices that use HDMI but don't employ HDCP (e.g. HD Home Camcorders) but with protected content HDCP handshaking becomes an obstacle because you have three "hands" trying to shake.
