How these HDTVs de-interlace 50i material is a black art and differs from manufacturer to manufacturer.

This is exactly how I've been explaining the various and differring reports on the 25p quality when played back on LCD's or plasmas. These devices, when fed an interlaced material (and this is how the V1 output, no matter in I or P mode), are trying to deinterlace. Some do it well, some not. But "deinterlacing the deinterlaced" is a big and as yet unexplained question. Therefore, it'd be of great value to be able to play back the V1E 25p material on a CRT HDTV - never came across any report on how such setup is performing, though.

Unfortunately, CRT HDTVs are almost impossible to find apart from a very low end Samsung TV which probably doesn't have the resolution to be useful. :)

I am pretty sure the Progressive problems of the V1 will be down to viewing devices and current NLE implementations.

Show me evidence that the OIS system in the palmcorder HV10 and A1 is the same, that you can't manually completely turn it off. Where is that stated? Who is talking?

I'm as much referring to what I've experienced with my own eyes and experiences, not from what "someone I know told me."

I'm not in that personal way, sorry If I hurt your feelings.
Evidence is that Canon writes black in white that the OIS can turned off. There is an on/off function. That I've seen bumping scatevideo's'. That the A1/G1 has a 20x lens which is completely different from a palmcorder HV10 lens and the OIS system to compensate with that.

You are right, lets call it a day, you started this OIS discussion with 'fat black letters' in this thread and repeated it. I just returned. Back to subject.

Agreed. Closed for now.
