SPC had nothing to do with the DVD release, which Jones is unhappy about.
Read the tweets backwards, most recent first:
Im actually quite upset right now.
UK DVD sales of Moon a healthy 120,000+. US numbers? Less than half that... due to huge number of "free" copies given to rental companies.
then they can split rental revenue with those chains, and pay the film makers... you guessed it... nothing.
Did you know that sometimes, when a studio wants to screw an indie film, they actually "give away" the DVD to large rental chains? ...
Just learned how we got "got" by the studio on Moon, and wont be getting any revenue from it. Very angry.
UPDATE: Later on, he took all these tweets down and posted:
Shouldn't try to understand revenue reporting. didn't have all the info. Being assured it's all as it should be... Will stick to directing!
Having particularly rough day today... going to try and keep my head down and concentrate on SC. Its going to be a fun watch, I think. :)
