Going via an analogue hole would be one way=2C but a pain in the arse. I wo=

bypass encryption though. Software solutions may show up...Seems there is one HD switch/multiplexer available which does though. http:=

on 2x TOSLink.)But obviously there is the worry that a new version of HDCP will be release=
tomorrow so bypassing in this manner is never ideal!Dale.

AFAICS=2C the prosumer video equipment you mention will not>=3B accep=

video equipment. I simply want something that can switch between>=3B=
mutiple HDMI sources (including consumer equipment such as BluRay/DVD&=
gt=3B players)=2C and then split the chosen HDMI signal=2C so that video go=
es>=3B directly to the screen=2C and audio goes to my computer for fu=
rther>=3B processing.>=3B >=3B Hence=2C I'm not really in=
the market for prosumer/professional video>=3B equipment. I don't ac=
tually want the video signal into my computer at>=3B all. However=2C =
there is currently no (consumer-level) standard (except>=3B HDMI) for=
