context: Yesterday my wife and I wanted to watch a new movie that had just hit the video stands.  I went to the local store which had a Red Box video vending machine outside of it.  I looked over the selections it had till I found the one I wanted.  I put my credit card into the slot for paying and purchased a copy of the movie to watch.  I took the copy from the machine and headed home after stopping at the store to buy some popcorn for the movie.  I placed it into the DVD and watched the movie while enjoying the popcorn.  The movie and the popcorn were great.  When I was done I popped the DVD out of the machine and went back to the store to return the movie to the Red Box video vending machine.  It was an excellent experience and I will definitely do it again.
question: is it DVD or VHS?
reference: the husband rented a DVD from Redbox
candidate: DVD format
