What operating system are you using? If you have Vista Home Premium, or Vista Ultimate, or Win7, Windows Media Center should recognize the card and allow you to tune the channels, and record.
Windows XP Media Center Edition should also work.
If you have just XP you will need third party software to tune the channels and let you record. Most tv cards come with their own software package for this purpose. GBPVR is a free program that might work with your card: http://www.gbpvr.com/
