Here's one frame from the original video as I received it on a non-commercial DVD, showing a typical dropout (the actor is Mandy Patinkin, while he was still in high school):
Here is a link to a few seconds from the un-modified original MPEG-2 file, showing a portion of the video with a fairly large number of droupouts:
1968 Video
I re-mastered the entire productions, using AVISynth to reduce noise & remove dropouts. I then used Vegas to correct color, adjust gamma, add chapters, correct rolling video, and more.
Hope this helps!
P.S. This is not a commercial DVD, and I believe was created by someone at the station for the performers involved.
[edit] I should also add that I actually do not know the chain of transfer from what was obviously (because of the date) Quadruplex 2" tape to the DVD that I received. I only guessed that it was converted to Beta SP and then to DVD.
