Hauppauge says: As an external unit connected via USB 2.0, myTV.PVR is flexible and convenient enough to instantly turn any Mac into a full-fledged Personal Video Recorder. Users can watch life TV in a window or full screen, pause live TV with instant replay and schedule TV recordings on a daily, weekly or once-only schedule. myTV.PVR includes a built-in hardware MPEG encoder, so the Mac does not slow down while watching, recording, or pausing TV. myTV.PVR also includes composite/S-Video and stereo audio inputs so users can connect to cable or satellite TV boxes, VCRs, camcorders, or DVD players. Users can also record home video tapes to disk in an MPEG-2 format.
