I didnt want to start a new thread.
I remember hearing that before they shot Enterprise season 1 they put an HD camera on the set of VOY im season 7 for a side-by-side comparison.
I think i was on a special feature of ENT dvd season 1.
I'd like to see that footage in HD.
It would be at least 5 years though as they still have 4 seasons of TNG to do and DS9.
