Hey does anyone know how to stop the PS3 from downloading Vita games? Whenever I buy or acquire a game through PS+ there is usually a vita version which I later discover is waiting to be installed to a vita (that has already been downloaded). This would be valuable to me if I were a vita player, but I am not.

If there is no setting I guess I have to traverse the download queue each time to weed them out. I know in some situations you can tell the PS3 to download specifically the PS3 versions by not clicking the vita versions, but other times it just downloads both.

You could use the PSN web store to claim your Plus games. From there you can select exactly what gets downloaded afterwards.
