I have just purchased a netcomm NB9WMAXX for my vista PC. I want to use my old PC, in another room, connected to a TV to watch my Avi-Divx's from the PC that that has the NB9.

I have considered running a lan cable but is this unnecessary?

Will a G router be capable of streaming this type of video from one PC to another?

If so is there any kind of PCI card that is recommended for the older PC?
