....on a DVD; where are the people who are doing it; sitting? And are they LISTNING to the show, as well as watching it? Because on a commentary that Dick van Dyke and Carl Reiner do on an episode of Dicks show; Carl says at one point that they're watching it without the sound.

Good question....I would imagine they're sitting and watching along, that's what I've imagined while watching a commentary.

Basically they're in some type of recording studio and are watching the episodes, usually with sound. Some shows have Video Commentary which might help you visualize it, for example: Boy Meets World: Season 2 and Roseanne: Seasons 4,5,8,& 9

I have those, I'll have to check out the commentaries on them.

ON SOME DVD'S SOME COMMENTARIES OF THE CAST OR PERSON BEING INTERVIEWED WILL POP UP AT THE BOTTOM OF THE SCREEN AS YOUR WATCH AN EPISODE. AND HE/SHE WILL EXPLAIN WHAT WAS HAPPENING AT THAT POINT OF THE EPISODE. I LIKE THAT IT'S LIKE WERE WATCHING IT TOGATHER. (IT'S NICE TO SEE WHAT THEY LOOK LIKE TODAY IF YOU HAVE NOT SEEN THEM IN A LONG WHILE BUT THEY ARE IN A STUDIO.

The only TV DVDs i have are the ones for Corner Gas, they take place in a little recording studio while the actors watch the show live (Presumably on a monitor) and as far as i can tell, ad-lib their comments on the spot!

what's "Corner Gas"? Never heard of it.

:yeahthat

I love to watch commentaries on any DVD I buy. My favourite commentaries are on the Buffy the Vampire Series DVDs. In most of them you actually learn stuff about the show, but all of them are funny as heck!
