That's strange, are we using the same file here?

I've tried a couple of different programs now and they all report the
format of the audio stream in question to be TrueHD. This is what the
program TSReader (http://www.coolstf.com/tsreader/) says about the
m2ts-file:

        Program Number: 1
        PCR on PID 4097 (0x1001)
        PMT Version: 0
        
        Stream Type: 0xea VC1 Video
         Elementary Stream PID 4113 (0x1011)
        
        Stream Type: 0x81 AC-3 Audio
         Elementary Stream PID 4352 (0x1100)
        
        Stream Type: 0x83 LPCM Audio
         Elementary Stream PID 4353 (0x1101)
        
        Stream Type: 0x81 AC-3 Audio
         Elementary Stream PID 4354 (0x1102)
        
        [...]
        
And according to this message:
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2008-June/048410.html,
0x83 is TrueHD:

        [...]
        > AUDIO_STREAM_LPCM = 0x80,
        > AUDIO_STREAM_AC3 = 0x81,
        > AUDIO_STREAM_DTS = 0x82,
        > -> AUDIO_STREAM_AC3_TRUE_HD = 0x83,
        > -> AUDIO_STREAM_AC3_PLUS = 0x84,
        > -> AUDIO_STREAM_DTS_HD = 0x85,
        > -> AUDIO_STREAM_DTS_HD_MASTER_AUDIO = 0x86,
        [...]
