TS Unprocessed is an profile available at the bottom of the list with other unprocessed profiles (if you're using the stock profiles.conf)
Copying the original happens only when the source file is a TS file, all other files are remuxed into TS files. You can skip remuxing also, but many features like closed caption extraction etc may not work since they only work on TS files.
