i tried the code
and for example
-i matrixbench_mpeg2.mpg -map 0:a -map 0:a -map 0:a -map 0:a -map 0:v -map 0:v
test.nut -map 0:a -map 0:a -map 0:v -map 0:a -map 0:v -map 0:v test2.nut
generates when i stop it:

Its not easy to read this and know which line represents which stream
also this is the same audio stream stored 7 times yet the statistics
look nonsensical, one would expect 7 identical bitrates and in fact
not 971kbit/sec for a vorbis audio stream with default encoding parameters
