because I am dumb. I was doing something else when I've read your reply and had to leave quickly. In the rush I typed 10 digits and copied them everywere. I should have numbered them most significant bit first too.

0_______ 1_______  2______ 3_______ 4_______ 5
76543210 76543210 76543210 76543210 76543210 76543210
00000010 00100000 Dev____ Sub Dev  Fun____  XOR( B2, b3, b4)

I hope I didn't screw up anything else. This so cool. No I can make sense out of my pronto codes for panasonic.

01000000 00000100 ...... :-)

I know very little about IR commands. Does each device uses unique Dev/Sub dev? Or can it interpret several Dev/Sub Dev function tables?

From brief look over some codes I have handy it looks like both learned and some codes I got from this forum use SubDev = all 0.

My learned code had device: 10010000 = 0x90 = 144

Can I find somewhere tables of the functions for a certain Dev/Sub Dev? Do all panasonic devices use the same fun set?

In a worst case I'll try 255 commands and see if one of them is discrete power on or off. As long as there are no deadly functions that will break my vcr I should be fine.
