I think the show you're refering to was a special that CBS produced to coincide with the release of the "Beverly Hillbillies" movie that came out in 1993 (to say that film sucked would be giving the producers too much credit!!) The special revealed that Mr. Drysdale was, indeed, a crook and that Jane Hathaway turned state's evidence against him and was currently hiding out in the Witness Protection Program. It also revealed that Elly May became a veterinarian and Jethro, following in Granny's footsteps, became a mountain doctor in Beverly Hills...complete with Granny's old mountain remedies. (Jethro also revealed that his true love was...JANE HATHAWAY!!) The special also featured testimonials from celebrities like Ray Charles and Hoyt Axton. I'm sorry I can't remember the name of that special, but I know for a fact that CBS DID offer it for sale on vhs. (mind you, this was almost ten years ago, bit I'll bet if you do a search on ebay, you might have some luck!)
