So I have some questions.  I was recommended to come here and join a little while ago by a user at another board who said these are worth it.  My questions are:

1.  How are these BD quality if they are downloads?  I have never seen anything download no matter where they are ripped from even come close to being as good as an actual disc.

2.  Where do I go to download this?  I went to some site listed in the first movie's topic, but the site had them broken down into 4 different downloads, and it was only for the first movie.  I was told to wait for version 1.2 to come out of that, but I cannot find anything for this one.  However, is the download broken into pieces?

3.  I download that img thing, but after reading about it, this all seems way too complicated to put together.  I mean, having to somehow splice the files into one large file without it actually showing and trying to copy them to a BD disc just seems way too complex. 

4.  Has anyone made disc art and cover art for these?  If so, where and what type of paper do you recommend using.  In fact, is an Epson Artisan 710 even going to be worth printing BD covers from?  I have never seen any printer be able to even touch the quality of an official releases cover art?

I think that is all I have to ask for the moment.
