Sample Input File

[Carl Eugen Hoyos]

Could you explain what the issue with the sample is?

Replying to cehoyos:

Could you explain what the issue with the sample is?

Either the rm header is being read wrong and it doesn't really have a third track, or it is being read right, and we don't support whatever this third type of track is yet.

Whether it is a bug or enhancement depends on which it is...
