L-220 DLNA lacks thumbnails on movies when viewed through Smart TV??

[elgius]

Hi folks,

just bought my first NAS (LS220) this weekend & dumped some mp4 (H264) on there to test streaming to my Smart TV.
It was successful, but the interface (Twonky?) is pretty poor? There were no thumbnails for the films & didnt seem to be anyway to organise the layout (you can search by various things but I was hoping for a cut-down Plex type experience).

Is there anything that can be done to upgrade Twonky or is that all we can do with the LS220? I appreciate it's not a powerful unit, & reasonably cheap really but just wondered if it can be improved?

Thanks,
Lee
