I`m building my first PVR .My computer specifications are in my signature .Is my computer good enough to run two tuners and watch a recorded show ? Do I need anything else to make the WinTV-PVR-500 MCE-Kit work ? Is there another dual tuner card available ? I need something to replace my two VCRs .Am I on the right track ? I`m using XP media as my operating system . Any suggestions for hardware or software are apreciated .
