    I use TMT5 and WMC.

    With some blu ray discs, I have to crank the volume so high (45/50) to get a normal volume level. 

    Normally, I keep volume ~18/50.

      Can you give some information about your audio configuration? Are you decoding on PC or in an external device (AVR, TV, etc.)?  Are there any commonalities with the soundtracks you are noticing the same behavior on (e.g. they are all Dolby TrueHD or they are all PCM, etc.)?

        Here is my setup:

        htpc => tv (HDMI connection)
        tv => audio receiver (SPDIF connection)

        My tv is a Sony Bravia and my audio receiver is a low end Sony 5.1 system.

          Can you check your audio settings in TMT5 and post those? It sounds like you are more than likely decoding audio with TMT5 and sending PCM audio (raw digital uncompressed audio) to your TV. This would mean that TMT5 is then responsible for defining the audio levels of thise audio samples. There are some dynamic compression options in TMT5 that you might want to play with. Typically, dynamic compression is used to decrease the dynamic range of the audio (dynamic range = difference between high and low). Most soundtracks for movies will be mastered quite similarly with respect to total volume. Some though may have more or less dynamic range which can alter your perception of volume. Also, try to correlate the audio type being decoded with the volume levels you notice. It is possible TMT5 could be doing something different if audio is say DTS-HD MA vs. Dolby TrueHD.
