I got a Hauppauge PVR150 running on Windows Server 2008 standard. First enable Desktop Experience then copy the following AX files from a Vista installation (windows/system32) to the system32 directory on W2K8. Cut and paste the commands in a batch file to register them. regsvr32 /s bdaplgin.ax regsvr32 /s kstvtune.ax regsvr32 /s ksxbar.ax regsvr32 /s Mpeg2Data.ax regsvr32 /s mpg2splt.ax regsvr32 /s MSDvbNP.ax regsvr32 /s MSNP.ax regsvr32 /s psisrndr.ax regsvr32 /s VBICodec.ax regsvr32 /s vbisurf.ax regsvr32 /s WSTPager.ax
