On: XBMC 11 is released

Why do you need a script to mark a file as watched? On Plex and XMBC you can easily toggle a file's watched/unwatched status from the navigation interface.

I store this watched status on a server that other people created. It is used to collect statistics of how many people watched a particular file. It also allows me to see what files I've already watched as I use multiple devices.

There is a mymediadb plugin for xbmc that does this. Can probably borrow code from there if you have your own backend thingy. https://github.com/netbrain/mmdb-xbmc-addon
