THe file is 2.2 GB and belongs to someone else. I can possibly provide a part of the file as a sample, but which part?
Thanks.

The issue with providing the whole file is copyright, mainly. I've extracted the first and last 100 MB.
The files are uploaded to:

At least provide the first and the last 100MB, ideally the whole file.
