Hi! Has anyone else had problems with slow disc access with their Sony DAV550? Not sure if it's been getting worse recently, but it can take up to 2-3 min to read a DVD/SACD and even then it won't always access the disc! Also, for multi-channel SACD should that be automatic and if I put it on dolby pro-logic 2 does that make it SACD multichannel? Thanks in advance for your help!
