I can't find the manual for your remote, so I don't know what the code for PS2 is for your remote.
Given your situation, I believe the PS3IR-1000 might have been a better choice for you. It has an internal infrared emitter and would make programming your remote easy. Unless your remote can be connected to a PC and programmed with hex codes, learning the code from another remote is the only way. However, all of the commands in the Discrete Off macro are on the PS2 remote, so you can program the macro into your remote.
Mihuta... Is that Romanian?
