Does anyone here know what's up with this?

On the ffmpegX homepage 'they' talk very excitedly about all the the formats that can be read including Video_TS.

Well, when running the program and trying to encode Video_TS to MP4 error message pops up and says that 'This engine does not currently support VIDEO_TS input. Use VOB input, or select a preset using mencodeer or mpeg2enc engines.' And so when I try to input VOB, VOB is greyed out. And as far as selecting a preset . . . I thought that was what I was doing.

Can anyone here clarify a bit what ffmpegX is trying to say? Thank you.
