"Loop" playback setting should be ignored during Convert operation
When doing a media convert (for example DVD to MP4), if the playback loop option is turned on (button on the main toolbar), then when the conversion is completed, VLC immediately restarts the conversion. Since the output file now exists, you get the "File already exists" popup, but there's now way to cancel out, it just keeps popping up if you close the dialog or hit Cancel. If you allow it to "replace", it deletes the just created file and runs the conversion again.
The only way out is to kill VLC in TaskManager or ProcessExplorer when the "file already exists" dialog is displayed.
The "Loop" button setting should be ignored when doing a conversion.
Also, the "file already exists" dialog should allow cancelling the operation.
