How to export error rates for each megabyte to CSV file?

QPxTool has a feature that allows exporting results in a QPx Data File.

When I tried to use it however, the message “Unable to create file: [path]” appears, so I could not examine that file to find out what information it stores.

But is there any way to measure the error rates for each individual second (CD) or megabyte (DVD) of the entire disc or a selected range, and export it to a CSV file (or JSON or any other format)?

I think that seconds and megabytes are the highest resolutions for error scanning on CD and DVD respectively, because these are the smallest units Nero DiscSpeed and QPxTool update at.
