Thanks for the reply, I think the player discontinued. Do you know the best place to find in a good price ?Yes, Subtitle shift is great, plus colour and other options, see pics.
MKV playback over Network is a strong point, via NFS or SMB. Atmos, DTS-X etc with only a minor concern in playing these formats back to back (very minor).
Playback of both UHD and BR Full (menu) Backups are possible too over the network. DLNA is supported, but functionality is varied dependant on software etc, and so I don’t use it.
