Do all the disc just have 1 interview on them?

I am renting 1 disc at a time, which set & wich disc of the set has an interview with J. Frid?

Each disc in each collection has one interview, with the exception of Collection 1 - Disc 1. That disc had a recap of the first 209 episodes.

Jonathan Frid interviews are on Collection 1 - Disc 2, Collection 3 - Disc 1, and Collection 5 - Disc 1.

Thank you for your help.
