Probably a bad idea to link to bootleg merchandise dvds since it is against forum rules.
That site should be shut done all they sell are pirated tv shows. Most of which are officially available on dvd. and the ones that are not they don't own the copyright to them.
Preservation is a grey area only as long as someone does not sell the unavailable as yet episodes to make a profit.
I'm surprised that guy is not in prison who owns that site.
