I've tried google, but I can't find any solid information. I would love some feedback from an owner that's gone through the process.

Thanks.

Cisco DTA30 for cable, Roku, Onkyo TX-SR606, and the Samsung LN-T4661. Would rather only use one HDMI cable to the TV from the receiver, but that isn't working. Any suggestions? Probably I'll have to use the optical out back to the TV, since the DTA is connected right to the TV right now.
