I have a Hauppauge WinTV tuner on my computer. I thought I was just going to set up Windows Media Center to record shows and set up a network share so I could play the MPGs on my GTV. Of course Microsoft has to record the shows in some proprietary .wtv format so I can't do this and I'm looking for another way. Is there an app that will let GTV behave as a WMC Extender? Is there another PVR program I can use that doesn't charge a fee for the guide info?
