I cannot detect any difference between -rtc and -nortc. My test 
methodology is to:

1. Use this file:
http://images.apple.com/movies/us/hd_gallery/gl1800/1080p/bbc-japan_1080p.mov

2. mplayer bbc-japan_1080p.mov -rtc
(observe that mplayer says my system is too slow at "A:  28.1")

3. mplayer bbc-japan_1080p.mov -nortc
(observe exactly the same result)

I also tried with -v to make sure mplayer was using the requested timing 
sources. It was indeed.

Is there a better way to test this?

Athlon64 3400+ (a bit overclocked)
Debian (amd64)
2.6.17-beyond1 (ck patchset + misc other stuff)
kernel CONFIG_HZ=1000
