Tried reloading 1.54 firmware again today, but popping still there on DD & DTS (not on stereo). Reloaded 1.55 firmware, same problem. Tried D1, D2, D3 & D4 digital inputs. All the same.

I'm sure it's software bug!

One disc that has particularly obvious pops on the left front speaker is the Phil Collins Finally The First Farewell Tour. If anyone has this, could you please try track 9 on Disc 1 (DD or DTS as it occurs on both). I get a couple of loud pops within the first minute or so, the loudest being just as Phil starts to sing. My type setting is "All Small/Mono Sub".

Thanks.
