My friend, I can help you understand as I always assumed this is what was going on and the source of your frustration. All this time you've been posting about the studios putting out inferior content, but, that is clearly based on the content you are getting second-hand by whatever source is flooding the web for you to find titles, which, really isn't a true representation of the content that is actually available.
Again, using your latest words about SOD, here is what I have for that last part of DSVR-723 (D). I only chose to acquire this part since it was the smallest and I wasn't going to grab the entire title to do my comparison.
DSVR-723d
File size : 2.62 GiB
Duration : 12mn 14s
Overall bit rate : 30.6 Mbps

Frame rate : 59.940 fps
As you can see, you are unsatisfied because of the quality of titles being provided to you from wherever you grab titles from, it is not due to the content being produced by the studios. I can only assume this is the case for much of the JAV you've been accumulating. And, really, if you think about the situation, you should not be surprised. If you've spent any amount of time here on Akiba pre-VR you would know that there are re-encodes, upscales, downscales, watermarks, all kinds of things that can degrade a title, being shared and uploaded again and again. This would account for your experience of drops in quality.
The way "uploaders" work, in my opinion, is always the most benefit for the least effort. So, those who want to get their content out as fast as possible for you to click on (to generate for them) they usually skimp on quality and go straight for quantity. They will get lower fare if they can since it takes less time for them to download/torrent or whatever the case may be, so they can then turn around and quickly upload it for you to get.
