I hate the Chaiyo situation, and the Japanese DVDs are out of my league price-wise. I have an 'unofficial" VCD set of the original series, but its quality is way under par, of course. One minute you're watching the United Artists' dub, then you see Japanese footage of higher quality and sound spliced in, before it reverts to the cruddy looking UA print. This happens in the Keyra/Jirass and Red King episodes where gore scenes were edited back into the show. But the J-footage was so awesome, I wish I had the series in that quality, with subs, in LEGIT form.
If Ultraman is part of MZ's "boot policy", then I apologize ahead of time, Megaloman. I'll delete this post if requested, but I just had to vent about the unavailability of the original Ultra-series on DVD.
