You have to use SMB shares.

I was starting to suspect something like that because the nfs shares are extremely slow on windows, they work superbly on my Arch Linux installation. But why are samba shares required over nfs which I assume can be tuned to be faster?

I'm trying to share settings between Linux and Windows, is this feasible? Also, can I have the windows machines link samba shares and Linux point to nfs shares if they point to the same folders, ie movies or something, or will the database interpret the sources as different and scrape duplicates of everything - one samba path and one nfs path file?

I don't know. You'd have to experiment.
