Query: An important notice!

After living in Russia for four years without any Trek, I had to buy the DVDs. It's been wonderful to re-live and share the series with my friends and we are all looking forward to DS-9 and Voyager as the season sets arrive.Only one small complaint about formatting. I normally skip the prolog "Space, the final frontier ..." and skip to the second track. However, the second track does not always take you to the begining of the first scene after the "commercial break". As a rule of thumb, if after 5 seconds you don't see the name of the episode, track back until you do. You could be missing up to 5 minutes!!!
