Yes, they are gone in 1.8 (actually they have been gone in the cvs
version for almost 2 years ;)).

'-b' has a 100% equivalent in 'y4mshift'.

man y4munsharp

y4munsharp is effectively the GIMP unsharpmask plugin for YUV4MPEG2
streams. It is also much better than the '-S' option was with the
old yuvdenoise <g>.
The defaults are sane but feel free to experiment (if you know how
to use the GIMP's unsharpmask filter then you know how to use
y4munsharp - the parameters and thei meanings are the same as in the
GIMP).

y4mshift -b xoff,yoff,xsize,ysize
y4mshift can also be used to center the 704 active pixels in the
720 pixel frame. Both vertical and horizontal centering can be
performed and you can use '-n', '-N' and '-b' all at the same time.
However if you are going to DVD you can crop to 704x576 (which is a
valid DVD frame size) - just thought I'd mention that.
