You guys are wonderful. Yes, the format is NEC. I built up a test box with Arduino. The MR's are made in the far east and are dirt cheap they all seem to use the NEC format. I hope this paste of the data works. I found this information on Technoblogy
NEC remote control protocol
This version of the IR Remote Control Tool decodes NEC format codes, originally developed by the consumer electronics firm NEC. For a full description of this protocol see San Bergmans's excellent SB-Projects site
[6].
The data is encoded using pulse distance encoding. Each bit starts with 562.5µs of carrier. A zero has a total width of 1.125ms before the start of the next bit, and a one has a total width of 2.25ms before the next bit:
The carrier pulse consists of 21 cycles at 38kHz. The pulses usually have a mark/space ratio of 1:4, to reduce the current consumption:
Each code sequence starts with a 9ms pulse, known as the AGC pulse. This is followed by a 4.5ms silence:
The data then consists of 32 bits, a 16-bit address followed by a 16-bit command, shown in the order in which they are transmitted (left to right) :
Note that there needs to be one extra pulse at the end to terminate the last bit.
