I am trying to install my hp avc-3610 dual tv tuner. I tried to download the driver or drivers from HP. I tried both sp29300, and sp30923. Neither worked. sp29300 came the closest to working, but while installing it asks for the adaptec driver disk. Apparently there is a file missing. The file it is looking for is avcuwfl2.sys. I googled this file and the only results in optaining this missing file come from one of the driver programs that want $30.00 for it. Surely there is another option. There are 12 HP tuners on ebay now, none with the original install disk. Everyone states to download driver from HP. What am I doing wrong?
