Hi,
I am not a big fan of PULSIN. It is sometimes hard to know what is happening so I prefer setting up timers to measure things myself. There are several posts in this forum how to use timers and it is really not that hard. If you pick a 16 bit timer and set the prescaler to 1:1 you can measure up to 65 ms without overflowing at 4 Mhz and 2.55 ms with a 8-bit timer and getting a nice resolution. The RC signal shouldn't be hard to catch this way.
If you have tried everything else, Timers might be worth a try.
