I think that this might solve that problem ... the *MUX*HD* shown here


I spoke with the vendor by email and they assured me that this unit would
"fix" that pesky *H*D*C*P* issue.

With that in mind, assuming that there is no *D*R*M* issue with capturing
HDMI output, any other suggestions as to how to capture that? It looks as
though the *MUX*HD* also has a DVI output which could be used for input to
some sort of capture device. Any DVI input capture devices that you folks
know will work with Linux?
