Apparently, HD DVD was not the final frontier for Star Trek. CBS and Paramount are giving the classic TV series its second high-def launch -- this time on Blu-ray.

Star Trek: The Original Series will blast onto Blu-Ray on April 28. The 7-disc set will include all 29 episodes from the show's first season, as well as a ton of extras.

One of those features will allow viewers to choose between remastered episodes and the original broadcast, to compare effects. If you want to get all old-school with the video, you can also have audio to match. The release will include the original mono sound, or you can pump up the volume via 7.1 channel DTS-HD Master Audio.

There's also a "Starfleet Access" option, which will provide pop-up trivia and picture-in-picture video commentaries throughout select episodes. Other features include an interactive tour of the starship Enterprise, rare on-set home movie footage, an inside perspective on what it took to transport Trek into the 21st century and much more.

The entire Star Trek: The Original Series promises over 24 hours of entertainment -- as well as a collectable Sulu figure from Diamond Select Toys (Blu-ray set only). Unfortunately, shoppers will have to send away for the figure, but you'll only have to pay shipping charges.

In case you've been living in a cave, the original sci-fi series starred William Shatner, Leonard Nimoy, DeForest Kelley, James Doohan and Nichelle Nichols.
