Well, as mentioned above, there are very few movies that make use of the rear channels, however, if you receiver has decoding like Dolby PLIIx, the rears will get much more attention. Also, I'm curious if you have the 22's angled towards you? Bookshelfs will not be as forgiving as Q's, but should still work well, especially in PLIIx mode.
You mentioned a meter, so I assume your talking about the Radio Shack SPL meter? Have you run the manual test tones from the receiver and calibrated all speakers to 75dB?
