Hi WinTv doesn't seem to be very stabe. I have to reroutinely restart it in order for to record. I was wondering if there 's an alternative that supports Hauppauge HVR-900H usb tuner. Also it should allow me to record from composite input. I'm using Windows Vista. I'll soon upgrade to Windows Home Server 2011 though.
You may get somewhere with DVBLogic. It's supposed to support several tv-cards and Windows Media Center and Windows Home Server. Although if you are in America it might not work since America uses another system than DVB.
