I am a bit confused with some of the options being requested, but looking at the above that you have stated on files size is very concerning to me. I am limited on my server disk space so if I have to compress files when I don't need to because they are larger than they should be, that is a problem. I also loose the MOV_TEXT in files when I compress movies or TV shows so that is a problem too. If the files sizes don't need to be compressed, I am happy.

The final size is the same of the file is the same 10gb so you do not need to worry about that.
As for the option to disable the parallel downloading/processing (and why it causes failures and buffer overruns) I'll make an example with v6001.
Lets say you download a 10gb video with 2 audio streams. StreamFab 6001 downloads and decrypts all the streams in parallel and to achieve that it has to do it by splitting them in small chunks:
Video stream : (Header.tmp + Header decrypted) + (1.temp + 1.temp.dec) + (2.temp + 2.temp.dec) + (3.temp + 3.temp.dec) + .... (N.temp + N.temp.dec)
Audio stream 1 : (Header.tmp + Header decrypted) + (1.temp + 1.temp.dec) + (2.temp + 2.temp.dec) + (3.temp + 3.temp.dec) + .... (N.temp + N.temp.dec)
Audio stream 2 : (Header.tmp + Header decrypted) + (1.temp + 1.temp.dec) + (2.temp + 2.temp.dec) + (3.temp + 3.temp.dec) + .... (N.temp + N.temp.dec)
then it merges/concatenates the temp files in the 3 big files.
But (and here lies the problem in version 6001) issues a command join/add "n.temp.dec" to the temp file stream, and then a delete command "n.temp + n.temp.dec".
So the disk constantly writes and deletes (or at least tries to delete) those small pieces..
Result=> SMR hdd's cannot keep up.
What I ask is to bring back the previous 5053 setting:
Download
Video stream : in one big temp file -> decrypt it
Audio stream 1 : in one big temp file -> decrypt it
Audio stream 2 : in one big temp file -> decrypt it
Or if they want to go with small chunks as it is now... At least do not issue a delete command for every chunk added (during the merge) but issue only the delete folder command after the merge is finished.
