If MuvAudio2 tries to play files that can't be played or have errors in them, MuvAudio2 will skip them and store information about the error. Once recording finishes, the MuvAudio2 Console will show you which files were skipped and the reason they were skipped. It will then give you the option to save a playlist of these skipped files with which you can use later to try to record these files once you have fixed the errors with these files.
