No, in my experience it is not "a hell of a lot slower." I haven't done 
any careful experiments, but nothing I've seen suggests it differs by 
more than about a frame per second, if any. Remember that most of the 
time spent transcoding is in the encoder. If you use the same encoder 
with the same options and same video input to both mencoder and 
transcode, it'll go at about the same speed. Of course, some significant 
time is spent in the decoder, but mencoder and transcode may be using 
the same decoders for DVD input anyway. They probably are using 
different resizers, so there may be a difference in efficiency there, 
but that may not be very significant compared to encoding time, 
depending on encoder options.
