My old sony dvp 536 has pauses that are noticeable when I play discs. I play the same discs on my Xbox and .. wha... they are not there! There "seems" to be no layer change! I know this must be down to some sort of buffer, but what "proper" players, eg: pioneer , sony, etc have these buffers? Which is the best player for a "seamless" layer change? any ideas?
