a couple things:
ebay will remove items upon a request from the 'copyright owner'. the owner can lie, and basically, if it's a smaller person (Site), ebay will put them on warning. a larger owner - call it a music company - can lie, and have those emails sent to ebay, and ebay STILL will remove the items.
i know this firsthand.
however -if you purchased the DVDs and they're legit, as you claim, you ahve every right to sell *the originals*. once you bought them, they're yours to do anything that doesn't violate copyright law.
unfortunately, contacting ebay directly is akin to dealing with moe, larry and curly - but the stooges had more intelligence. you'll ikely have to get on the ebay live chat, and explain that you have the ORIGINAL product, it'll take some hoop jumping, but you can get it listed again.
or you can contact vladuz, and he'll be happy to list it for you with a pink heading! (joke for those who know what ebay's been trying to hide the past few months).
disappointed that TTM would try to stop it, but c'est la vie.
