Video Formats

I've had a few questions about the video formats that TP/WHS can handle. The TiVo hardware can only handle MPEG-2 (mpeg2video codec) encoded video and supports 720, 544, 480, or 352 x 480 resolutions. It works with either MP2 audio codecs. DVD models can also handle the AC3 audio codec.

If a video file is not encoded with mpeg2video MP2/AC3 audio with one of the supported resolutions, TP/WHS will use ffmpeg to encode the video. It encodes the video on the fly into MPEG-2 720x480 with MP2 audio.

ffmpeg supports many video formats and codecs, including h264, m4v, mp4 (includex xvid/divx), mpeg1, mpeg2, wmv. The only format I have had trouble with his WMV-HD and a couple of old QuickTime MOV files.
