New Firmware & Metatags

Hi

Just wondering if any one can help I have been archiving my DVD collection onto the hub and got most of the cover art etc for my movies. On the previous firmware there was a folder called metatags that had all the cover art etc in it for each movie just wondering where that is now since the introduction of the new firmware. Does any one know if the new firmware allows manual additions to cover art etc?

The metadata is stored in the same folder as the movie.

Thanks!
