Thanks for the reply. I use both XBMC on my old XBOX and WIIMC on my WII. From what I heard, both are using dvdnav but in XBMC my DVD navigation is working with smb shares. Is it because of the lan adapter not being performant ?
All I know is that there isn’t enough buffering on dvdnav over SMB for a pleasant experience (it’ll keep rebuffering every few seconds), so that option is disabled.
