I believe this unit was part of a DVD box set. It contains 2 DVDs, and is titled Season 1, Volume 2, Discs 3 & 4. The DVDs are still in near mint condition. 

It contains the following episodes: 

-Home

-The Storm

-The Eye

-The Defiant One

-Hot Zone

-Sanctuary

-Before I Sleep

-The Brotherhood

Ideal if you want to get a taste for the show or need to replenish your collection.
