It is there, just missing documentation. 1.0pre7 is rather old, CVS has 
documentation for -hr-edl-seek .

-hr-edl-seek is not garunteed to work correctly with -ovc copy, but it 
should work ok in this case.

That is odd.. There have been some updates to edl in mencoder since 
1.0pre7, you might want to try cvs.
