When we have a same movie several times, they are grouped together wich his fine.
But to decide which is the best quality one it could be also usefull to see the size of each files from the presentation screen.
We already have the codec and quality description but this size file info could be very usefull when codec are not correctly read.
Here I have to go to edit menu to read the file name and then go on my NAS to check the size of each of them.
