#660 Stuck in loop

[windcheetah]

I am using DVDStyler verson 3.0.3 on Linux Mint 18.1 64 bit with the MATE interface.
The program would appear to get sutck in a loop when you use the file browser, with what it says, is an invalid file.
A couple of things, why is it trying to process that file, it was not the one I'm using to make the DVD, also it the file plays fine with VLC.
