I just spent all afternoon in vain trying to teach a TSU-3000 the codes from a Samsung SIR-TS360 HD Satellite Receiver. If anyone out there has these for a Pronto, please e-Mail me at "[email protected]" I will gladly pay for these codes if necessary. If you have the codes for an MX-800 or MX-3000, I might be able to use one of those to teach the Pronto. I have access to the URC MX-700, 800 and 3000 at the store where I work.
