A brief rundown on Six releases:
UK- There were 3 'single' releases before the season boxes, the quality was good for season 3 episodes but poor for earlier material. Then the boxes for season 1 and 2 came out with irregular quality (ranging from good to abysmal), and 2 errors: season 1's Operation Firefly is missing the 'boat whittling' scene, and season 2 merges The Bionic Woman with The Bionic Woman Part II, removing some shots from Part II in so doing.
Italy: I only have Season 3. The color quality is flat and looks to come from an old transfer, there are burn-in text translations for the episode title and signage in the episodes. Original english soundtrack is included. Welcome Home, Jaime is missing as it has been since 1978, moved to The Bionic Woman season 1. The Secret of Bigfoot (both parts) is missing, apparently this was never shown in Italy, not sure why. TSoBF was on one of the UK singles, so you can get it on DVD still. The season 3 material on the UK singles is head and shoulders above this release in quality, but the Italian release is the closest to a complete season 3 collection in english right now.
Mexico: Season one here has the holy grail for "Original Broadcast Version" fans: the three 1973 TV movies in their 90 minute form. NTSC transfer means the audio is without the PAL 4% speedup, and the color correction here is quite good, yet the transfer is marred by interlace issues.
France: The French have been releasing the shows without english soundtracks, so I've not gotten them. In addition to season boxes, the French have issued DVD singles- which have now spanned all of season 4 and even cracked the lid on season 5. Two episodes, The Bionic Boy and The Thunderbird Connection, are VOST, ie with original english sound. The episodes are presented in syndicated, two-part form. I'm given to understand that the French have the original version of Wine, Women and War instead of it's 2-part re-edit, and Six includes Welcome Home, Jaime - I don't know if this is the original credits or not.
There are rumors the Germans may be doing a release; I hope so, The Bionic Woman season 3 was top quality.
Obviously I'm one of those Mr. Willis referred to as to my criteria for satisfaction; I will say that getting the shows out as syndicated would still be a marked improvement. Good unedited transfers, original soundtracks, broadcast versions, in that order. I won't let the perfect be the enemy of the good. The syndication changes were a bitter pill, but the priority at this point is to get the releases up to the 1978 level. I would love to have my complaints reduced to the persistence of those 9 changes, rather than complaining about poor and incomplete releases.
Of course, I'd love to have no complaints at all. If we can get them, I'd like the original broadcast packages. The 3 TV movies are the important things- the reassigned episodes should be restored and the movie events rejoined, but the 1973 movies are the main complaint. The crossover episodes would be a great gift if both shows could have them rather than the Solomonesque solution from 78, and the movie events play better at one sitting, but the 73 movies were demolished by the reedits. I could go on and on.
