i like collecting any available extras, featurettes, commentary tracks, etc with any movie or show in my library, but more often than not i have a pretty hard time finding them. i know they're sometimes on youtube, but it's very hit and miss, especially with newer movies; and as they're often included in bluray, iso rips usually have them but i'm not particularly knowledgeable on how they work to be able to rip only the extras.
so i guess the question is: is there any tracker/forum/other source that hosts extras (either with the movie itself bundled in or not)? any suggestion is greatly appreciated.
If you download the ISOs, with MakeMKV you could get the extras pretty easily. There would be different tracks that you could extract to your liking and dispose of the rest.
