Try this, it forces 4 repeats of the signal for each button press. Change the number in red to force even more repeats...
Upgrade protocol 0 = 00 AF (S3C8+) PB v3.11
52 36 11 8B 12 95 45 04 08 00 FA 03 D4 00 FA 01
E0 0F 8C 07 D0 07 BC E6 0D 04 8D 01 46
End

Ok Robman, I tried to increase the repeat rate ... and the m$ dongle was still picky. sometimes it wouldn't take, and sometime it jumped 2 or 3 block, so i've been messing with the first two bytes that fixed the x3ir, thinking something might make a difference. Well ive also searched through some forums, and i found 3D 92. I thought it can't hurt ... now, the remote works way better than the m$ remote, but the x3ir's range has dropped again. it still has about 8 feet range, but i'd like it to be about 15. Any advice on how to increase this new code's duty cycle to eventually compromise the two recievers to good ranges? I've been playing guess and check and i think it's time for the experts help.

Changing the first 2 bytes to "3D 92" converted the frequency from 57kHz to 38kHz, and it also dropped the duty cycle down to 29%.
To keep the freq at 38kHz, but increase the duty cycle, try these codes...
52 7d = 40%
67 68 = 50%
7c 53 = 60%
Just in case you're wondering how I'm figuring this stuff out, I'm doing this all using the PB (Protocol Builder) spreadsheet. So, if you're interested in dabbling yourself, take a look at it.

Thank you very much Robman! ... I found the protocol builder and i messed with it. I should have mentioned this, but it never registered as important to me ... i replace the IR receiver on the m$ dongle with one that came with a TV card for a computer i built. I didn't really know that receivers had certain frequencies that they ran on ... so my dongle replaced receiver ran somewhere are 30 whereas the x3Ir ran up about 58 ... I finally settled on "47 6B" which is 44kHz and 40% duty cycle. It's amazing to think of how complex these remote signals really are and that the slightest bit of difference can really change things. Thanks again for your help! My xbox is now finally setup like i want it. I really appreciate you running this site and all the time you've dedicated (as well as others) to gaining the knowledge to do this kinda stuff.
