Are you sending single or multiple copies of the IR? Most of the receivers need to see multiple copies to set their AGC and receive threshold so most protocols send more than a single copy.

Excellent! Working perfectly now
Switching the transistor and LED around so that the transistor is sinking current, and changing the bias resistor to 1k did the trick (Thanks keithdoxey and ardhuru)
It now has pretty much the same range and capability as my regular TV remote.
Thanks very much to all for your help.
My next step is to get it working with my Receiver. Getting that working should be much smoother now tho. I can actually change the PWM frequency on the fly by writing to the appropriate registers, so even if my other equipment works on different frequencies it shouldn't be a problem.
