Configure GR Standalone to display .FLV files *Solved*

Hello,
I would like to know if I can select that GR displays in the selection screen of ADD ITEMS other file extensions, for example *.FLV

At the moment GR displays Type of Files: "Gallery Items" which are JPG, GIF, AVI, etc
I would like it to include FLV, even if I select Type of Files: ALL FILES, FLV does not appears.

Thank you very much for your support

Update: was solved installing a newer version of the ffshow, jptran, etc
