Re: HD to SD downconvert - Best Results Inquiry

Here's my beef, though, with Kona 3. In the HD-SD downconvert, I see a rather noticeable halo around edges (esp in contrasty areas and GFX). When we do the same conversion through a Teranex mini, you don't get the halo, but it feels ever-so-slightly... over-processed? A little in-organic.

And whilst on the subject, it seems as though there are options, when sending dubs/conversions out of house, that some facilities just go deck-to-deck (HDCAM SD-SDI out to Digibeta) and other route through a (full-sized) Teranex or UKON. Is there a difference? Is the in-deck downconvert any better than the convertor boxes? Is there a a best case scenario for one process over another (ie: frame rate changes; aspect ratios)? Primarily, I'm a fanatic for quality (much to my staff's dismay), so any insight is appreciated.

And sorry for being a little off-topic. ThxD
