Edision picco s2 problem audio/video channels DVB-S2- DolbyD

hi, i have edision picco s2 for a long time, and it worked perfect until a few months ago. It turns out that mainly DVB-S2 channels (Dolby D audio), the audio is ahead of the video. Neither version of the software solves the problem, nor the newest. Before this problem did not happen. Any solution? Thank you

This problem appears to be fixed with the older firmware 1201.
