I am trying to use either the philips pronto series or the home theater master series (perhaps the mx 800) to control a commercial dlp projector - nec hd6k. Certain features (like turn off) require that the IR signal be actually be sent continuously for about 3 to 5 secs. Other features require a two stage macro which also requires that I have longer IR transmission time than just a blip.

Which remote would have the feature to control the length of the IR transmission?
