I never thought I'd buy another component that wasn't in the URC IR database, however, I couldn't pass up 30% off at our local Walmart. So, after some (Alot) playing around with Make Hex and an OFA remote and reading threads on this site, I thought I'd share the following info:

Sanyo DP32648   32" 720P HD-LCD TV

Using MakeHex and Hex2CCF (Thanks JohnSFine)

I have uploaded a MXD device file in the URC MX Text Series Files Section with what I think are the more useful functions.
