What can I do to correct the IR blaster signal between my RTV 5040 and the Motorola 2244 Set Top Box. The blaster is sending a channel change signal but the STB does not seem to receive the correct channel number, resulting an incorrect channel selection. It seems that a single digit channel selection to he RTV results in the on-demand channel displayed by the STB. A two digit channel number input to the RTV gets a single digit display and selectuon on the STB. I tried fine tuning the IR code. I need some help.
