As usual despite the program having a setting to change the ratio the DVD Creator failed to do so. Also as usual, when I tried burning the same content using Bluray Creator it did what it was supposed to.
After all that I realised the Leawo dvd creator did actually also feature the option so I tried that and of course it worked perfectly reinforcing the opinion that the DVD Fab dvd creator is a pointless waste of time that needs some serious updates to make it work properly
