The 2000XP Expert uses the Philips chipset, better choice than the ancient BT878 found on many others - higher color depth video, and stereo audio processed by the main chip itself.
The card's design is OK too. What stands out is the internal audio connector. This lets you use your mainboard's AUX connector if you have that, to eliminate the rather silly loopback cable round the outside that'd occupy your sound card's Line-In plug.
Also, I've found Leadtek's software to be generally working for the vast majority of systems - something you absolutely can't say about the stuff from high profile brands like Pinnacle and Hauppauge.
