Before install the WinTV-PVR 150/250/350 I recommended this doing this first. Check the box "Ignore -Install all files, regardless of file signature" that way you don't have to put up with that dran warning box. After install the WinTV-PVR 150/250/350/Freestyle board in a free PCI slot. 1: You should see Hardware Wizard check the box "Install from list or specific location" then click the next button. 2: Check the box "Search for the best driver in these locations" then check the box "Include this location in the search" then click on Browse button. 3: Click on your CDrom or the folder where unpack base driver kit is at then click OK button. 4: Click the next button 5: If all gose well you should this page and it should copy some file. 6: Click on Finish button. 7: On CDRom or folder where unpack base driver kit is at you fine setup.exe run it select your Language. 8: Clik OK button 9: Check or Uncheck what you want. Note: Don't uncheck MPEG SW Decoder you neee them. After it done install everything it very good idea to reboot (I recommended this).
