When you blast is the flash on your bug a short, dim flash or a long, bright flash? I have had a similar problem from time to time. I'm not sure whether IRSS isn't correctly learning the command and saying it is or isn't correctly blasting. Look for the long, bright flash and keep re-learning until you see that. When I'm learning commands, I have the best luck when the remote I'm learning from is placed directly in front of my receiver (almost touching).

Effectively i have seen these two behaviours (short, dim flash or a long, bright flash), but resulting the same.... do not work. Very srtange and i really have no idea of a way to investigate.....
