SVT 150 projector isn't storing programs well at least i don't think it is. i don't have a remote for it so i tried using the memory button on the back. i presume that the process is tune to correct channel on prog 1 then press the memory button. turn over the channel and back again and the program isnt there. having read the instructions it only refers to the 2 buttons on the remote which isnt helpful when you don't have one. Is this normal or have i done something wrong.....?
