I have got the Droids and Ewoks videos from a YouTube channel, but I don’t know if they are as good a quality (they might be the exact same videos which someone has simply uploaded there). But they don’t include the great artwork either.

I have actually found a couple of web stores selling DVDs, but again the quality of the stills doesn’t look that great, e.g. RetroTV Memories (https://www.retrotvmemories.com/products/ewoks-cartoons-3-dvd-all-35-eps-complete-star-wars-1985-86/).

Although with the only options being video captures from TV or VHS tape, the quality is never going to be spectacular. 😦

Edit:
I’ve just picked up my emails and someone else has sent me an invite. Many thanks. 😃
I’ll give that a try a bit later today.
