Freeview STB info website. Most Freeview boxes have
scart outlets to transfer the video to the TV. This is difficult to transfer to a TV PCI card as most DO NOT include the scart socket. You may have to get a Freeview box with a modulator to input to the TV card co-axial input socket. A scart to SVHS + audio
from cable universe
may be suitable or scart to three RCA phono plugs
(composite, AudioR AudioL) or scart plug to composite video and stereo mini jack plug - it all depends on what inputs you have on your PCI TV card.
There are also PCI and USB TV cards from Avermedia and Hauppauge which include the Freeview channels.
Lots of choices. Check out some boxes click here and try the links - especially the Radio and Telly link.
