i have the same problem:
tv-card = A-DATA DT1
O. S. Windows Vista Home Premium
When i try to instal the software for TV-card it says it requires Windows 2000 or higher. But at the end of the instalation it says that W Vista HP and the tv-card software are incompatible. What can I do? I bought this card for my old laptop but it doesn't have 2.0 USB, now that I have a laptop with 2.0 USB I can not instal it because of Vista
Help, pleeeeeaaaasssseeeeee

Thanks a million!!!
