I kind of want to chime in on the double-dipping argument over Blu-Ray verses every other video format. I collected all of the Golden Collections and most of the Super Stars releases (and the Mouse Chronicles set). Those are not the only DVDs featuring Looney Tunes and Merrie Melodies shorts, but when it comes to repeats on DVD (and released-on-DVD shorts coming to blu-ray), I mainly care about whether they were released in any of the above-mentioned sets. And I know that most of the Super Stars releases and Mouse Chronicles do include at least one repeat from the Golden Collections, but at least the amount of cartoons not on previous Golden Collections outnumbers it. When it comes to new Looney Tunes releases, I don't care if it was a bonus short on a non-Looney Tunes DVD release, or even if it includes one of the few remastered cartoons that doesn't appear in any Golden Collections, Platinum Collections, Super Stars, or Mouse Chronicles (among the few are A Wild Hare and Porky's Duck Hunt). It would be great if Warner Home Video would put out a DVD of all the shorts that were newly-remastered for the Platinum Collections. I'm not really surprised that the Platinums are mostly comprised of cartoons that had already been remastered and released on DVD years ago. It means less work on them (I wonder if they did any extra work on the already-remastered shorts).
Of course, back in the VHS era, I pretty much didn't care about repeating shorts on VHS. In fact I often thought up my own wishlists in my head for videos I wanted to see made and shorts included, often including stuff that I knew had been released on video. Of course I didn't have many Looney Tunes VHS releases... Of the commercially-released shorts VHS compilations I only had three Warner Home Video releases and quite a few public domain tapes (in addition to recording many off TV). It really wasn't until I saw The Bugs Bunny Video Guide around 1999 that I started caring. When the first Golden Collection came out, I was disappointed that the majority of shorts had already been released on VHS, though the following volumes would include more new-to-video-format shorts.
