[WTV Unprocessed] Description=Creates WTV (MPEG-2) files by copying the video directly. It does not resize, remove black bars, deinterlace your videos or select audio language. Use this if you have high quality HD recordings which don't need processing. order=copy copy-remuxto=.wtv copy-audiodelay=skip FixedResolution=true SkipCropping=true
This will only with the latest BETA release due to a bug in the older ones. This should preserve the original audio and video.
Also you can override the framerate while remuxing, open mcebuddy.conf, under the ffmpeg remux section change -r <auto> to -r 60000/1001 or whatever you want it. You can do the same in your ffmpeg-video section also in profiles.conf
