I was looking to get some info on any of the demo disks out there. I'm a newbie and looking to buy a few of these but before I get ripped off I'd like to find out what is legit and possibly value of disks. It seems like there are 9? disks of DTS demos. Does DD release something similar ? What would you guys recommend be a good disk(s) that aren't priced too crazy ? I found a disk on e-bay that contains a lot of trailers and intro's but it's a decent price which makes me wonder if it's legit. The seller's id is hometheatersignsanddemos. Link deleted by administrato. DO NOT POST LINKS TO EBAY AUCTIONS! - MR Even though seller says that this is not a copy I'm curious... Has anyone bought from this seller or better yet, does anyone have this DVD (DOLBY DIGITAL DTS ULTIMATE DEMONSTRATION DVD DEMO SET) ?
