Using a 100mbit/s network you'll have a hard time getting more than
75-80mbit/s over under real world conditions. No way getting 165mbit/s
over. You'll be losing frames like hell.

Not for the decoded stuff, but for the MPEG files, yes, that's what I'm
doing at home. 

So - the machine is too slow to decode MPEG2 in realtime, and the network
is too slow to get decoded video over. Maybe at a lower resolution like
320x288. If you need more you either need a faster machine or a hardware
MPEG2 decoder PCMCIA card. Don't ask me which of these has decent Linux
support... -> http://pcmcia-cs.sourceforge.net/ 

Please remember an MPEG2 PCMCIA card needs a ZV port - check your Vaio first.

USB could be a way to go if your Vaio supports USB2.0. But I pretty much
doubt if a Celeron400 machine has USB2.0 to begin with.
