I've recently purchased a Philips dvp3960 dvd player, and have programed my Mx-500 to control it by using the learning method except for one problem I haven't been able to solve. I cannot get a command to work twice in a row. IE if I want to fast forward, when I press the button the first time it will cause the dvd player to go to 2x fast forward, but when I press the fast forward button the second time it will stay in 2x fast forward and not increase to 4x as it will with the oem remote. Any ideas?
