Does anyone have any information as to why Paramount has not provided ANY audio commentaries by cast OR crew from ANY of the Star Trek TV shows on dvd to date? Virtually every other major SF and fantasy show (to name a few genres) has at least one or two commentaries per set. I find this sad and a real wasted opportunity. The extras on the ST sets are often decent but of course could be better. However, this blatant omission is quite irritating. Thankfully, the ST films are not slighted in this respect. It would have been great for example to have Mike Okuda or Rick Sternbach add even a text pop-up on some key episodes. Anyone have any data on this one?
