I have a VU solo 4k (openatv 6.4), a zgemma h2s (openatv 6.3),and a PC all using lan cables on a network. All can see and use files in all units except the zgemma h2s which does not show the VU in a network scan and therefore can not play any files on the VU. The zgemma can play files on the PC and OpenWebif can access both boxs from my PC. Can anybody help please.
