Country code shouldn't be a problem since this is only a bit that has
to be checked by the player soft- or hardware, unless you have a third 
generation DVD-ROM which also checks the country code by itself.
The Linux software players don't support country code ;-).

What kind of CPU do you have. I tried it with a Dual Pentium III 450, where 
nist ran without problem ( in this case it was a binary I got from the 
net) and on my notebook with a Pentium 233 MMX ( here I had to
recompile the source). On the notebook it was a little sloooooow, but
what do you expect. If you use mpeg2dec it is supposed to be a lot
faster, since they have included a lot more optimization. Maybe you
should download a free vob somewhere and try if that works (maybe at 
http://www.trailer-inside.de/). I just got the Star Trek Trailer and
it plays fine with nist on my notebook (mpeg2player -na -vob -f
<filename>  (no audio so I won't disturb my hardworking coworkers)). 
It also works with mpeg2dec, but is much slower (extract_mpeg2
<filename> | mpeg2dec -). I have no DVD right now, but I will try it
at home.
