Is this possible?

Hello everyone

So here is what I am trying to do. I have a projector setup and am running the HDMI signal from a Mac Mini to a Home theater pre pro. (Integra 80.3) Now I love to listen to vinyl and surf the web, but with this pre pro I can only assign the hdmi signal to the channel I am currently listening to. So If I listen to a record I get no video signal.

I had an older pre pro and it had a bypass mode in which I could bypass the current "channels" audio and play sources direct. In the case of a turntable this worked great allowing me to listen and surf the web in 12 foot wide glory.

does anybody know if there is a current pre-pro that has a direct bypass feature? If not any ideas on how to make this happen? I know I can run the video signal direct but I love to see the OSD, so with that in mind any suggestions?

Thanks in advance
