The ebay seller from Malaysia is almost certainly a hokey copy.
The fact it's region free is usually a very big indicator of it being an unlicensed release (and depending on who made the disk it may be little better than a poorly encoded fansub).
Depending on the anime there may or may not be BD releases, DVD is still considerably cheaper to author and replicate than DVD (there are far more DVD facilities for example).
If you look at
www.animenewsnetwork.com they normally list any English language distribution including streaming.
It looks like there is/was a simulcast/streaming with up to 1080 quality and English subs, but I'm not sure if it's still there.
