Hi Paul--

Personally, I've used Boujou aand exported the camera movement data to Maya. 
It is actually pretty easy to use, and certainly has a much flatter learning 
curve than Maya itself, but I think all the modern motion tracking s/w is 
fairly easy to learn these days.  Boujou is great in that it is 
resolution-independent, but it is rather pricey, somewhere over $5 grand, I 
believe.  If your friend's studio is working with standard def DV, they 
might want to take a look at The Pixel Farm's PFHoe; it is supposed to be 
the same software engine as their full-featured (and full-priced) PFTrack, 
but PFHoe is $99 and I believe there are demo versions you can get.  PFHoe 
is limited to standard definition DV, but for $99 (or the demo version) it 
might be a good thing to play with to evaluate their anticipated workflow.

Maya has motion tracking software built in as you mention Max does; it is 
called Maya Live... I don't know anyone who uses it.  I've been studying 
Maya at the very Maya-centric Gnomon School, and they mention it is there, 
but they don't teach it at all, instead teaching Boujou and Realviz 
Matchmover.    I suspect 3DS's tracker is similarly limited as your friend's 
experience suggests...

If you are shooting live actors against green screen and want to put them in 
a virtual set, all I know to do is place tracking markers (X's) on the green 
screen and use those to track the camera's movement with.  There are 
recommended practices about the shape and placement of the markers as well, 
but I haven't actually done this particular workflow as the tracking 
projects I have done were putting CG objects into handheld camera background 
plates.

The Pixel Farm's web site is http://www.thepixelfarm.co.uk/   If your friend 
is interested in learning about motion tracking workflows and "best 
practices" for production, he might want to take a look at some of the DVDs 
on motion tracking offered by The Gnomon Workshop 
http://www.gnomonworkshop.com

Hope this helps!
