H265, Serviio & LG

Hi All,
I have an "LG 65UN81006LB UN81 Series - 65" TV and I have an issue with seeking (rewinding & fast forwarding) with H.265/X.265 files. H.264/X.265 are working fine. (Side note, can anyone explain the difference between the H and the X please?)
Is it a limitation of my TV or a limitation of Serviio? (I have the latest Serviio version, Pro 2.4)
Please could someone explain, and if there's a way to get it to work with my current setup, please explain?
Many thanks,
Kev.
