I recommend you report it as a bug (Help -> "Send bug report" from Scribe's menus). Make sure you include the exact make and model of the recorder and any information about how it's configured (such as file format, quality setting, etc.). Please also upload a problem file with the bug report - if you can't send the original due to privacy reasons, could you make another 46 minute recording of the radio / TV? Finally, please include your email address in the bug report, so we contact you for more details if needed.
