Supress duplicates in Collections and other lists

[egn]

Hi,

to get more Netflix and Amazon like frontend I use my complete video archive to generate a genre based toplevel directory for movies and series, into which all the videos are hard-linked arccording to the assigned genres. As the nfo files may contain multiple genre tags per video, they appear multiple times. 

The issue now is that generated libraries like Collections and other lists may contain the same video multiple times. It would be great if processing could be extented to suppress the shown duplicates. This could probably discovered by testing if the corresponding nfo files are the same.

Thank you for the support.

Cheers
Emil
