A bit of a story here: I would like to be able to quickly and easily turn on/off captioning on the cable TV box. Normally this would require 10(!) button presses.
It's hard to be sure, but I expect that no commonly available universal remote control can be programmed to automate 10 button presses.
Having formal training in electronics, I easily used an Arduino to record all the necessary IR signals (via a sensor/demodulator) to accomplish the function.
My first attack on this problem was to make a program running on an Arduino that would accomplish this function. It worked, but it's such an over-kill… Also, you need to wait for it to boot (1? second). Edit: I could try modifying the board to shorten this boot time.
I don't have an EPROM burner, otherwise I would wonder about clocking a counter at 38 kHz and addressing an EPROM and using 1 bit to operate an IR LED (via a 2N2222).
If I were to stick with an Arduino, I think I would use the PWM to make the pulses. (Before I enabled a 555 astable which did the driving).
What is the easiest way to get this done?

I would recommend TV-B-Gone Kit and modify their available firmware to match the code sequence you would like to output
