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 Wizrad. 2: Click next button. 3: Check the box "Search for suitable driver for my device" then click next button. 4: Check the box " Specify a location" then click next button. 5: Click on Browse button. 6: Click on "Look in" down arrow fine your CDrom or the folder where unpack base driver kit is at then click Open button. 7: Click OK button. 8: If all gose well you should this page then click next button. 9: It should copy some file 10: Now you should see this just click next button. 11: On CDRom or folder where unpack base driver kit is at you fine setup.exe run it select your Language. 12: Clik OK button 13: 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).
