As yet there does not seem to be an NTSC conversion from Mentor's TV cap. If by the time I get it from RapidShare no one has done it, I will definitely undertake the project, have no fear.
The only concern is it's been said that it's interlaced, suggesting they did some weird pulldown scheme rather than the traditional speed up.
I won't know what I'm looking at until I have it and can check out the video frames and listen to the audio side-by-side an NTSC version.
