Someone with a DVD-R(A) drive can do region coding.  A DVD-R(G) drive
can not.  The former costs $xxxx while the later costs $1xx.  DVD-R(A)
(A for authoring, G for general purpose) are also up in the $10+ per
disc last I checked.  The pioneer DVR-201 and such I believe are
DVD-R(A) drives.

And yeah many older players can not play any burned discs, while they
can all play the stamped discs no problem (as long as the software and
firmware don't have any arguments).
