From my side, all needed information (tuner, epg) should be included in the already mentioned thread. Maybe some more users can post additional information in order to notice commonalities or differences.
Isn’t worth a shot to look into change log between version 1.21.1.3876 and 1.21.2.3943 since with version 3876 commercial skip worked as expected? There must have been something changed between both version respectively the version 1.21.2.3939 in between.
