The take home point I'm trying to keep across is that you haven't given any valid reasons for it. At best, it would be an unreliable work around for problems that would be better solved in a different manner. Descriptive audio should be handled by selecting specific tags in the stream. Inconsistent audio volume should be handled by implementing Dialnorm, or by adding a rolling normalization routine during playback or as a batch job. If the mixer is resulting in too high or too low audio, then it is a legitimate bug that should go on trac, not the wishlist.

MythTV has traditionally provided options for any and every setting someone wanted to change. This is a bad design paradigm. When you give users options, there is a fair chance they're going to use them, even if they don't understand their meaning. There are many examples of options in MythTV that were added for rare configurations or hardware, but are enabled in inappropriate situations resulting in worse problems than they fix. The last several versions of MythTV have made an effort to remove these kinds of settings, replacing them with automatic detection, or removing their functionality all together. This is that kind of setting that will be misunderstood by most, rarely used for its designed purpose, and result in more problems than it solves.

=== Audio Level During Commercials ===
You are using MythTV, which does have the ability to skip at will. Telling someone to simply skip commercials when they complain about them is most certainly not trolling, but rather simply stating the design intent of the application. If the commercial detection does not function properly, fast forward. If you do not like the fast forward behavior, use the time skip instead. Default skip length is 30 seconds, set for the default commercial length in North America. You can change this if Germany is different. Alternatively, hit one or more numbers, followed by an arrow key, to jump that many minutes in the video.

Variable volume in a recording is a problem, but the solution is not to choose MP2 over AC3 tracks. The problem you are experiencing is because AC3 has a parameter called [http://en.wikipedia.org/wiki/Dialnorm dialnorm], which seeks to allow full use of dynamic range, while ensuring the audio is properly loud for playback. MythTV blindly ignores this parameter. Television shows broadcast using this parameter may be significantly quieter than commercials, because MythTV is not applying the proper gain during playback.

=== Stereo Downmixing ===
+
=== Commercial Detection ===
MythTV applies a matrix downmix when playing 5.1 audio over a 2.0 output. The front and rear channels are each reduced in level, and then mixed together to retain the same sound intensity as in the original. This is the same behavior as nearly any other video player. If the mixer is not outputting the same overall sound intensity as the input, then that is a bug, not a feature wish. The only known problem is that in systems without SSE support (PPC/ARM), MythTV falls back to using ffmpeg mixing, which results in low volume levels.
+
The bulk of MythTV developers, and all of those who have tinkered significantly in the commercial detection algorithms, are located in the US. While that means the algorithms are tuned for, and work reasonably well with, North American television content, it unfortunately means performance in other markets may be poor. This is something that really needs someone in the area with access to significant amounts of location specific recordings to fix. As cliche as this seems sometimes, patches welcome. --[[User:Wagnerrp|Wagnerrp]]
  
=== Commercial Detection ===
+
Some British users have had luck using silence detection to mark commercial points. There is a hackish script on the wiki that wraps a tool intended for use with single-file mp3 albums, and manually produces a commercial list. A proper audio analysis mechanism in mythcommflag would likely go a long way to improving accuracy for everyone. --[[User:Wagnerrp|Wagnerrp]]
