VJ Compression

I need to disable vj compression: man <????> or which file does 'novj' go in? At one time I found the answer on GOOGLE but misplaced it. Now, I cannot find the method for disabling vj compression. ISDN isn't working quite right with it enabled. Thanks! -- ..."Yogi" CH Namasté Yoga Studio "If music be the food of love, why can't rabbits sing?"
