Moved from always buggy WinDVD and PowerDVD (same s***, sorry) to ArcSoft TotalMedia Theatre 3 and now looking for silent install switches... Tried setup.exe /s/v/qn but it finished with ResultCode=-3 in setup.log. It seems I need to enter serial number somewhere... Also there is an update for it - totalmediatheatre_3.0.1.120_3.0.1.160_update_all.exe which doesn't support even /s/v/qn Please help.
