What regions are they?

I've mounted single-layer with iso9660 fs, but dual-layer will do strange
things, as it can only read parts of the files. UDF and iso9660 don't use
the same case on the filenames, either (one is all lowercase, the other 
upper).

I've seen people just barely run Xine with a single PIII 450 - if you get 
SMP working, it might help a bit. At least one of the major video decoder
libraries is multithreaded.

Does the ATI driver support video-related features, like fast YUV decoding
or motion compensation?

Don't worry about that; it makes no discernible difference if you print to
the console. The main CPU hog is not the decoding, either - it's the block
transfer from decoded data to the display.

libdvdcss 1.0.0, libdvdread 0.9.2?

If you're using only one at a time, you're safe. Is your motherboard UDMA 
33 capable? My previous DVD, a 6x Creative, managed 23MB/s in read tests
on an older motherboard (1998 make).
