I don't know what the problem might be. I have heard about a conflict between the Twinhan and one specific tuner card, but if you've taken that out, there shouldn't be a problem, however it may be that Windows grabbed the wrong driver if the old tuner driver is still on the hard disk somewhere. Have you tried to uninstall the driver for it in the device manager, and then when it comes up found again make sure to aim Windows to the directory where you have unzipped the latest Twinhan driver file? There should be some CAB files and the DTVaudio.sys and DTVvideo.sys files in that directory when you unzip the file, and Windows should be able to install it properly if aimed at that directory. If it still doesn't find the hardware, then I don't know... you might try installing it in another computer to make sure that the card works. My card shows up both as an audio/video device and as a network card.
