I think you are wrong...  there is an option for the -tv named *fps* - 
it determines framerate for tv video capturing, so:

mencoder -tv driver=v4l2:width=352:height=288:chanlist=us-bcast:channel=11:norm=ntsc:fps=10 tv:// -o tv.avi -ovc lavc -oac lavc -endpos 10

should works (and it works for me).
