Version 1.2.0 doesn't change anything in the file conversion process itself, but brings with it a new function: right click conversion! Just right click on any supported filetype and select "Convert with MC-TVConverter"! You can enable this function via the MC-TVConverter settings in the "Context menu" tab. Select the profile you want to use for right click conversion and add the link to the context menu.
This new function also enables you to drop a file on the program icon to convert it!
