Actually, I read Toonboy's post as if he mentioned Swat Kats in his post, went to look for it on amazon, then noted that, yes, it had been released on DVD and made a joke about it.
As I noted with other things Warner's released, they are among the "better" companies out they for releasing stuff, even if a lot of it is "on-demand / DVD-Rs" as the Road Rovers, Swat Kats and Ed Grimley all are.
I might even imagine - though I'd remain mostly unconvinced - that Warner's bigger problem when it comes to their release schedule isn't so much waiting for 20 years,* as it is with having the entirely of their library, as well as all of Turners and Hanna-Barbera's to get through.
*Though yes, I do believe that that was - and for some companies (even Warners) still is - a thing.
Reading one of the reviews on amazon was quite informative about the apparent state of the DVD.
According to the review, the "Russian Name Song" / "Sonovovich" from "A Day in the Life" is the only scene to have been removed. Episode titles are the edited ones (so the odd original titles like "Reigning Cats and Dogs Part Three." are "corrected" to remove the nonsensical "Part Three").*
He notes in his comments that everything else is accounted for, including the infamous Diana divorce scene.
*Which, I'd admit, saying a standalone episode is "Part Three" does fit with the humour of the show from what I can recall, and I think should have been left as was.
