Hi, using Switch to extract audio files form a m4v file is not working. The m4v file uploads correctly, when I 'convert' (to apple lossless format in my case) everything seems to work, but I end up with a small file that does not include the complete audio track. Only a few minutes of it (original track is about 1.5 hours) are actually converted and the software reports no errors. When the limited converted file is imported to iTune no sound can be heard. If I convert the same file to flac all works fine. Any Help? Thanks in advance
