More than two years later, I am struggling with the same problem. The RF option is still there in the Options menu of PDAWIN's TV Remote Controller 5.5 and pdawin.com does not respond to e-mails (I have sent them three during the last three months). I don't wnat to tape some clunky thing with batteries in it to the front of my PDA. When I get a round tuit, I am going to take a CF IR card and try to convert it into a CF RF card. Assuming I get this to work, is anyone else interested?
