Hmm, well that they already do in 2ch formats (compress more to get it
louder). In ac3 case I rather think it is ignorance.

In case of Pro7, Sat.1, ZDF you have one seperate mpa and ac3 track and on the
ac3 track you only have ac3 transmitted - either in 5.1 or 2.0.

In a perfect worls, yes. :-) But usually ads are eual loud, so that is not the
problem.

You already have if you watch a 5.1 movie: Commercials on ac3 track are to 99%
2.0 (except one Yamaha ad for av receivers, which is 5.1 - guess why).

Yes, true. but I think loud low frequs are not that bad (except for the
neighbors ;-) than eg 1kHz at 120db... I never measured the loudness I listen
too, but I am not listening movies at soft volumes. ;-)

Oh, well, I already have but because of stress...(it comes and goes...)
