Hi everyone. More questions about bootleg DVDs!

I have been looking for Digimon series with Japanese audio. The Japanese Digimon DVDs are extremely expensive, and the US and European DVDs don't have Japanese audio. Someone on another forum told me the US releases have heavily edited video, so the Japanese audio doesn't fit. It appears that most other language dubs use the US video track, while Cantonese and Malay dubs use the Japanese video track (so can include the Japanese audio). But if the DVDs are not properly licensed, all the money is going to scammers, and not the people who made the anime.

I read many of the old posts about this. Also wondering, would a licensed DVD always be encrypted and region-locked? (Is region free always pirated?)

And 17 episodes on an 8G DVD is still 470M per episode. So why is the video quality worse than smaller-sized fansubs?

I bought this one when I didn't know much about DVDs:

17 episodes on a DVD, low quality video, region free and not encrypted.
The government censorship sticker points here:

An old post said VBG has licensed some anime, but also sold pirated things:

Also seen a Savers set by Glorious Media Sdn. Bhd:

Again this has 16 episodes on a DVD...

Is it possible to check if these companies have a licence? Some people in the old posts seemed to know how to do that.

Some signs of a bootleg are low quality packaging, low quality video, bad subtitles, and putting many episodes on a DVD.

Some anime are licensed. If the box has information about the licence holder, maybe it can be checked.

Easy to get fake KPD Tulen stickers.

The government censorship board is only making censorship approvals and is not concerned whether the release is properly licensed.

Most other anime, I can buy a US or European copy including Japanese audio. Digimon is strange because the English dub edited the video track.

The US version of Digimon Adventure is $50, but it's English dub only.

The Japanese ones are like 10x that.

If VBG really licensed Digimon Tamers, it's possible that I still have a pirated copy of it...
