Hi there, cool I got the same vaio model as you then. Finding it great to use. Well there is a way, i'm researching into this idea myself as I need it also as a input to use my CMT-SE5 tv menu's. But it would be cool to watch TV on the laptop while on the move as well.
Something like the AverTV Cardbus would work info available at this site:

The price is reasonable at £55 from stores such as:
http://www.maplin.co.uk/
and http://www.mediaatlantic.com (being the cheapest).
Hope this is what your after, i'm looking into saving up for this myself as it would be great to have a AV video input as my camera isn't DV and I can't use the iLink 
Will.
