it seems that the region check in the drives isn't implemented very
reliably... the people of videolan (who made the libdvdread and libdvdcss
libraries) claim that their code bypasses this lock with most drives
(without any firmware hacks and such). however - of course i haven't tried
this and don't know about the legal status of all this. most of all i do
not advise to use or pursue any of this. i'm just passing along claims
that i read on the web. of course i am against breaking laws and such...
if there are any that prohibit any of this.


well... stupid politics aside:

by now it is more or less clear that xine's performance issues on freebsd
are definitely related to how xine ueses the pthreads implementation of
freebsd. i have contacted Daniel Eischen about this and hope for guidance
:-) so i am confident that within the next weeks xine might also become
the video killer app for freebsd ;)

Xv drivers are of course another matter entirely. the situation on freebsd
is even a bit worse than on linux. although it's getting better. the xfree
project is doing great stuff... not much that can be done about that,
except buying hardware of vendors that support open-sourced (free) drivers
for the important features of their cards.

cheers,

Heiko
