Quick question. For a MPEG-2 video in an MKV container, will Pytivo remux the MPEG-2 video into a compatible container or will it do a full re-encode?
I believe it will remux if it recognizes that the MPEG2 bitrate is not too high for the Tivo.
The newer wmcbrine versions can choose to remux or transcode the video and audio separately. So a MKV file containing MPEG2 video and AAC audio would have the MPEG2 video stream be remuxed (-vcodec copy argument to ffmepg) while the audio stream would be transcoded to AC3 (-acodec ac3 argument to ffmpeg).
Conversely, if your MKV has h264 video and AC3 audio of bitrate 448K or less, then the video would be transcoded (-vcodec mpeg2video) and the audio would be remuxed (-acodec copy). However, since AC3 bitrates higher than 448K can't be handled by the Tivo, they get transcoded to AC3 at 448K (or whatever you set your audio bitrate to via your conf.)
