The bright purples, reds, and greens of the Enterprise interior shine on Star Trek: The Original Series - Vol. 26's full-frame transfer, which looks great considering the time period and original source material. Although some minor defects do arise here and there, the overall picture is impressive and provides a nice presentation of this cult television series. There are fairly grainy elements in the transfer (especially in the second episode), but they aren't a problem because of the age of the product. The 5.1-channel audio transfer utilizes all elements of the sound field, and this is especially evident while music plays during the opening credits and tense moments of the stories. Although the scope and force of this track is limited due to the age of the soundtrack, it does move nicely through the sound field and use the rear speakers efficiently. One particularly impressive moment occurs in each credits sequence as the Enterprise flies across the screen. The sounds move straight across from the front to rear speakers, and the effect, although simple, provides an enjoyable experience. Each episode contains well-done English subtitles and the original television trailer. Each preview lasts for about a minute and presents the dangerous action scenes in order to draw audiences to tune in for that episode. Due to the large amount of episodes being released by Paramount, it's difficult to imagine much more in terms of extra features.
