Hi Nick,

I reloaded the firmware (1.55) again yesterday and re-typed both with my own settings and the standard 5.1AAA type setting in the 568. Same problem with the pops! In the past, I also tried going back to V1.54 of the firmware, but the pops were still there.

I know that the fault lies in the 568 as I've tried different DVD players, amps, cables, subs, speakers.... If I switch to any type setting other that "All Small/Mono Sub", the problem disappears. I'm now virtually certain that it's a bug in the 568.

Any more ideas? Keep 'em coming....

Thanks.

Steve
