Whites are visibly blown out on the without ES18 capture, can tell pretty clearly in the title credits where the actor names are in white see attached. Hard to say if the ES18 capture is also blown out, could possibly be just "less" blown out. Could be on the tape that way if a second generation tape too.

Those scrolling vertical bars towards the end look like they were caused by ground loops, but hard to say if it is on the tape that way or if that's a result of the current setup. You want all of your capture equipment and PC hardware plugged into the same power strip to try to prevent that.
