From a matter of convenience I could actually appreciate what they are trying to do.

Binge watching TV on disc, especially DVD, is frustrating. If you aren’t using the extra content (such as commentary), streaming is much better, as you can binge more episodes at a time or watch certain episodes without having to switch discs.

If I was unaware this was available on a streaming service I had, I’d appreciate the reminder. But I’d appreciate it more at or before the main menu, not during the content, and certainly not more than once (or reset when the disc is removed).
