I decided to give this one a try from Radiient:

[Link: radiient.com]

The tech guy there said that they were not aware of any problems with my hardware and their units. They also have various remote file formats (CCF, MX, etc.) so you can hopefully get by without the "Pro remote". If not, you can get it for $19.99 more. I did not need the RS-232 on the more expensive unit they offer.

As a follow up to the above, I received the unit and appears to work without any problems. I even moved DVD HDMI and PC HDMI to different inputs to make sure all inputs worked equally well....and they did. So far looks like it will be exactly what I need.

Thanks to everyone for suggestions,
Don
