Just how rare are these things? As an aficionado of failed formats, I've collected a few working CED videodisc players and every title put out on the format, and over the last year have been getting all the cheap HD-DVDs I can find. I've managed to find 4 D-Theater movies (a few showed up at Big Lots a couple years ago) but it seems impossible to find anything to play them on. Every time I've checked EBay for them, a few tapes come up but no machines. I don't know if any that do get sold go for a lot of money, or are just regarded as junk by most people (I'm hoping the latter since I don't have a lot of money to spend.) I know the tapes will only play on "D-Theater" machines- there are several other machines that are just D-VHS but those are only good for recording things in digital. If I'm not mistaken, just like early DVD players, encoding for DTS sound was a later addition and the first models of D-Theater decks won't output it.
