Well, I spent a large portion of the afternoon with Ms. Barbra Streisand in two TV specials: BELLE OF 14TH STREET and COLOR ME BARBRA.
First off, whoever mastered the original videotapes to DVD used the entire image all the way to the edges meaning that on the left side of the picture, I see video image artifacting not meant to be seen when I watch the 4:3 picture on a 16:9 TV. When I expanded the picture to fill the screen, the edges get lopped off, of course, and then the offending artifact isn't there. I'm thinking on a regular TV, the normal overscan would obscure this stuff, but when you're seeing everything possible to see, the lines running down the left side are definitely there.
That said, it's easy to see why BELLE OF 14TH STREET didn't make a big hit. Jason Robards can barely carry a tune, and he sings a fair amount in the first vaudeville sequences. As a tribute to vaudeville, complete with a (too) lengthy excerpt from THE TEMPEST, I can imagine the at home TV audience just would have gotten bored with it before it was half over. Naturally, they'd miss the concert sequence at the close which is the best thing about it. (Barbra also sings an entire number - "Liebestraum" - in her head voice, stronger than I ever would have thought possible, even for a singer with her unique talent.)
