I use HIGH and LOW instead of pulsout, with a pauseus in between, repeated every 16mS and it seems to work out fine for a futaba S148. Pulse width for the S148 is defined as 600uS-2400uS, with a midpoint of 1500uS.

By running the servos off a different power supply than the PIC, you'll avoid any brownout resets, which are particularly noticable under any significant servo load. Obviously you have to provide a common 0V reference voltage (ground) between the two.
