Hey Guys - I know someone in an earlier post mentioned that they were getting the messages that their tuner card couldn't be communicated with. I have solved that problem on my system with the following set of commands: regsvr32 /s Mpeg2Data.ax regsvr32 /s mpg2splt.ax regsvr32 /s kstvtune.ax regsvr32 /s MSDvbNP.ax regsvr32 /s MSNP.ax regsvr32 /s VBICodec.ax regsvr32 /s vbisurf.ax regsvr32 /s bdaplgin.ax regsvr32 /s ksxbar.ax regsvr32 /s psisrndr.ax regsvr32 /s WSTPager.ax I grabbed those files from my Vista 32-bit install and it works (they will be under system32 and need to be copied to system32 on your 2008 install.) You can put the commands in a batch file for ease of running them. It just registers a whole bunch of ax filter files that aren't registered by default. My TV (Hauppauge HVR-1600) now works in DScaler, but I still can't get the WinTV software working. Hope this helps someone.
