None of the current DVDs of the Fox Chans are legal. They're all bootlegs. Certainly some, particularly those sold by dennisflicks.com and torysmysterymovies.com are very good quality. They are all sourced from TV showings on the fox movie channel.
The Vintage Playhouse set has been routinely panned for its poor quality.
As Rush said, the official releases are coming soon (probably starting in March) from Fox Home Entertainment. You will get much better quality for a cheaper price. I encourage you to wait for those.
I hope they put a reasonable price on them. The $99.00 is pretty stout.I purchased 50 old horror classics for $19.99. Pretty good quality. A more reasonable price. I think FOX quit showing them so they could sell them, not because of presure from a few Chinese.
