Query: Rating the DVD not the Series

I am not going to contradict the reviewers that have raved about the series, I think that as a Television series it's very good. But if Ken Burns considers himself a filmmaker then he should be using the full video and audio range available to filmmakers. The Full-screen format and the flat sound were very disappointing. The sound recordings of the music weren't even stereo. Let alone worthy of the reproduction capable to DVD.And a note to PBS, I really really really Hate, the forced commercials at the beginning that went on and on and on. With, of course, the fast forward and skip buttons disabled. I'll think twice in the future before I buy a DVD associated with PBS.
