While I don't know any fixes for xine, I *do* know that changing NFS
from udp to tcp helped me *a lot* with latency.  Make sure it's enabled
in your kernels, and add the tcp option to fstab.  Do some tests and see
how it works.  It's been a while since I did it but I had huge changes
especially on large file copies / moves.

Failing the above mentioned idea, I'm out of ideas.  But let me know how
you make out.
