At least one product, though, the Hauppauge HD PVR, encodes analog HD output, as produced by cable or satellite TV boxes. Most cards of this type are designed to encode standard definition analog (NTSC, PAL, or SECAM) video signals. You can transcode to MPEG-4 after recording to save space, if desired, but this requires post-record processing and will degrade quality slightly. The main drawback of this type of card is that you're limited to the video format and encoding options supported by the manufacturer (usually MPEG-2). Most hardware-encoding cards output an MPEG-2 stream, which can simplify backing up to DVD. ![]()
