Yes through using DirectShow.

Never tried it but if there are DirectShow drivers for it then I think 
it will work.

No VLC doesn't use hardware decoding cards. It does decoding in 
software. It can however read encoded data from PVR' cards.

I hear the 250 is more stable when using with VLC. But a PVR-350 does 
work too.

The VLC on the server side when using a PVR-350 doesn't do encoding it 
only does muxing and streaming, because the 350 already encoded the stream.
The VLC on the client side does the decoding in software.

PVR 350/250 -----> VLC streaming ---------- network --------> VLC client 
(UDP) -----> output.
