CCR definitely developed huge legal (and interpersonal) struggles which led to early break-up of the band and endless bad blood to this day. However, I have read a couple of times over the years that the specific cause of their performance being left out of Woodstock film and album releases was that John Fogerty considered the performance sub-par for them and vetoed its release (he was quite the perfectionist, but maybe also control-freak in the eyes of fellow band members):

"At the wee hours of the night, CCR took the stage for a sleepy Woodstock crowd who had just finished mellowing out to an arduously long performance by the Grateful Dead. John Fogerty of CCR refused to allow the concert to be put on the documentary as he felt that the circumstances created a performance was not good enough to be documented."

I'm sure John Fogerty would be the first to tell you that it was everyone else's fault but his and if only you knew what he had to put up with, you'd understand how wonderful he is and awful everyone else is (particularly, Doug and Stu). Repeat that for three hundred pages and that's his biography that I had the misfortune of buying the other day.
