[streaming] Re: Streaming MPEG2 from Hauppauge PVR150 using VLC for Windows?

[list at scttransport.dk]

That would be appreciate by many I think, I know people who are planning to
use the pvr150 with vlc, and I could imagine myself getting one too if I
need more cards at work. Since it seems like a nice cheap product.

Let me know if u see any progress on it.

Venlig hilsen :P
