OK, I haven't gotten very far, but there is one interesting observation:
vlc plays my homemade NON-encrypted DVDs just fine (except for the
DVD menus, on which for some reason it errors). This kinda hints that
VLC is not finding/opening libdvdcss even though I'm using the one
from the nux repos, same as the source of the VLC RPM I have. 

One would think that nux's VLC would work with nux's libdvdcss, but
this evidence makes me wonder...

If nux is here, or if anyone here uses nux's vlc and libdvdcss with
SUCCESS, I'd appreciate hearing from them.


I'm not having any luck compiling libdvdcss from source... using
rpmbuild to create a RPM I keep getting errors about "unpackaged files
found", and can't figure out why or how to solve it (yes I've googled
for solutions).
