Hope someone can help. I recently purchased the 88+ but have a few problems. Sometimes when I put dvds in, they just start randomly playing a chapter. For example, when I put in finding nemo, it started playing a special features documentary. Sometimes, I will press chapter forward, and it will go backwards, I will press status and it will go to the set-up etc. Also I can't get my subwoofer to work when playing a CD. I am going from the arcam (the front l&r and the sub) into the denon a1sr's analogue pathway external in. The test tone does work, but unless I set the denon to +15 for the sub I can't hear it, and even then it is very low. Hope someone can help!
