Ive had a few problems with my R1 copy of Alien when playing in DTS, with the seemless branching to the directors cut. When it cuts back from a branched part, the film goes all jittery and then pauses. However in DD it doesn't. At first I thought it may have been the disc, but have read elsewhere about sound dropout problems on the Denon A11 (which mine has experienced) and that being something to do with the laser pick-up. Has anybody else experienced this issue or know where the problem lies?
