Sorry ... my two cents whether you like it or not.
All this is nonsense, you won't convince, better yet convert, anyone by explaining or even by presenting absolutely all the facts about producing and authoring. Even though there are undeniable fact about all these, when brought up thorough a forum, at the end, they are just opinions...
Anyways, these discs are as professional as professional get. In my opinion
they are even better than what the studios had produced (no disrespect to anyone). Not profiting or having a "commercial venue" for these does not mean that they are not professional. Also, just because the creators
of the discs are not specific to the industry doesn't mean that they are not professionally made. We might not be in the specific profession, but the work speaks for itself, and the tools and software used to create these is the same as the software used for the Blurays you and I buy.
Not being encrypted or not having specific country codes means nothing, these discs are targeted for commercial/personal use, that meaning you and me. If suggesting that commercial use is lesser grade than professional use, that is absolutely wrong. Furthermore, I think the commercial vs. professional terms are being miss-used in this instance. In the electronic industry the term commercial vs professional would be correct. For example there are professional grade monitors vs commercial grade monitors. We all understand that. Regarding Blurays, these discs in particular, there is not such a thing. In this regard would be more comparable to what is done in the retail industry... for commercial use vs. personal use, which would mean -- to be sold somewhere (for profit) vs just for the end user, that usually translates as FREE.
Now regarding the productions of the discs, if the intent would be to mass produce these and actually have physical media to distribute then yes there are certain steps, specific to Bluray production, that only certain companies can do before they are mass produced, however that has never been the intent of any of these projects.
Finally, just a big thanks to Steve for the first and V2 discs. They are very professional and a must have for AV setups.
