Figured I'd just try and ask if anyone has something they'd be willing to share through services like mega, gofile, etc. I'd be fine with just the audio and syncing it to video myself if it'd save anyone's time. I'm just gonna spitball a list of the ones I know of and don't have. If anyone wants to jump in with requests or shares that aren't listed, that's fine too.

Beavis & Butthead's first movie
Regular Show season 3 (dvd has some for select episodes)
Avatar The Last Airbender (presumably the bluray has the same ones the dvds did)
Family Guy
Johnny Bravo (I've heard S1 has some)
American Dad
Freakazoid (s1 dvd has 3, s2 has an extra called A Full Season's Worth of Commentaries in Five Minutes or Less")
Simpsons (season 13+ or movie)
Wall-E (there's 2 on the criterion set)
Pokemon films (english, The First, 3rd, and 4Ever)
