how much CPU would it take to capture and encode video from a non-PVR capture card so that it can be muxed with the audio from a soundcard? I ask because I happen to have an older WinTV card laying around. I'd even be willing to accept a lossless capture format to allow for easy live TV with AC3, with the ability to convert to XviD later if I decided to keep the recording.
