The Roddenberry Vault blu-ray has a special pop up feature for several episodes (Space Seed, City, Tribbles).  When I access this feature the video inserts are there, but the talking heads are muted. Nothing I adjust in the audio options bring their voices on.
Is this a defect of the disc, or am I missing something in the set up? Can anyone help?
