server 2008 doesnt contain the hardware compatability for tv cards you have to add it yourself by adding certain files from vista
you only know this because you get the error coming up to which files are needed if you use the ADD legacy hardware method
to get tv tuners working copy these files from vista into system folder then register them in run
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
