JC & Rob,
   Some advantages of doing a stabilized transfer over doing the 
stabilization in post (Flame or Henry) are 1) minimizing video processing - 
if you're using a compressed format (DCT, DigiBeta, etc) the pixel shifting 
done in stabilization will give you a (very slight, admittedly) hit when 
recompressing. Ampex and Sony demoed their compressed dvtrs using pixel 
shifting (H&V) to show worst case degradation in multigenerations. Bottom 
line - a very minor effect, more theoretical than visible.
   2) If you use Flame for stabilization you need to worry about the 
degradation from 601(YUV) -> RGB -> 601 color conversions. This is a much 
more significant effect and can be very visible and objectionable depending 
on program material.
   3) Blanking - post transfer stabilization of images implys that the 
blanking will now be variable. Depending on the material and degree of 
stabilization required this can be very minor(nanoseconds) or major 
(microseconds). If the telecine is well maintained and the film is in good 
condition then it will generally not be significant but is something which 
should be kept in mind.
