I guess no one mentioned Wonder Years. I freaking love this show and it took ages to be released on DVD due to the music licensing matter.
Throughout the whole series, only 14 songs have been replaced on DVD (http://www.tvshowsondvd.com/news/Wonder-Years-The-Complete-Series/20182) but we’re still lacking those.
However, if I recall correctly, Netflix had all the episodes with the intact broadcast audio with the exception of the opening credits, as they replaced With a Little Help From My Friends with a cover by an unknown artist.
Of course, the DVDs are much better than those old TV-Rips floating around, but have anyone tried to restore those 13 episodes?
