yes my mono encodes also show A/V offset. When launching mplayer from ssh, one can adjust/view the calculated offset with +/0 keys, and I can see that for my 22khz mono mp3 encodes there is a calculated offset of +560ms. (visible in mplayer display)

The offset seems to be identical regardless of encoder bitrate or vbr mode. The 560ms was observed with

-srate 22050 -channels 1 -oac mp3lame -lameopts lowpassfreq=11000:q=7:vol=2:aq=8:mode=3:padding=2
