[MPlayer-users] B-frames and interlaced encoding

Hi,

I read here:
http://www1.mplayerhq.hu/pipermail/mplayer-users/2003-December/040946.html

"B frames require big motion estimate search radii and are unfriendly to 
predictive motion
estimators and interlaced coding requires you to motion estimate a frame 
once
as a frame and then a second time as two fields."

Is this true? Why not estimate only as two fields (unless you specify 
mbd=2)?
Wouldn't it solve the B-frames problems with telecined and interlaced 
encodes?
