Record directly to DVD recorder

Hi. Just wonder if anyone out there has a dvd recorder in his/her computer. I am looking to buy one, thinking about the Pioneer one. I have an ATI AIW Radeon video card with TV tuner. Would like to know if I can record a TV show directly to the DVD recorder or I have to capture it first to my hard drive as mpeg file then burn it to dvd? My second option is to buy the Pioneer home deck dvd-recorder which I think can recorder directly to the dvd-r disk but it’s very expensive. Thank you.

Don’t think you can burn it directly to DVD from the live feed.
For best results you best save the live feed to your harddisk, eliminate the commercial brakes and then see if you can perhaps suffice with a CD-R instead of a DVD-R
