Just bought a Denon 1910 - nice machine, but the JPEG playback is slow. My previous player was 4 yrs old and didn't support JPEG playback, so I have no performance comparison. The Denon is taking 10-12 seconds to change from one image to the next - but the manual says it should only take 5 seconds. The images are burnt to a Kodak Picture CD format. They are from a 5 mega pixel camera - if the disk can only read at normal DVD playback speeds, I'm not surprised it is slow, but they why does Denon (and other brands) advertise playback for JPEG? Is this problem with my machine, or are my expectations too high?
