The signals image in the last log shows an interrupt on every rising edge, and so whatever I thought I coded wasn't it. 

This image is perfect. The pink signal on the top is the interrupt being triggered every time the IR receiver gets a hit. It's inverse, but it's not a big deal.

Now I need to count the time in between the pulses.

That's more like it. Make sure you add plenty of margin to the timing values, as the timing for remotes isn't very precise. I had to increase the accepted margin of error in my code multiple times, as it would sometimes not accept an IR signal. Now it's working perfectly.
