Is it possible to save,copy,rip or stream a blu-ray movie to your pc via the LAN port rj45.The bd1250 can see the shared files on pc,but I cannot see the BD1250 from the pc.
As far as I know the BD1250 doesn't export any DLNA or Network Sharing functionalities, it can merely access File shares (and even that it doesn't do it right).
So no, I don't think you can save, copy, rip or stream anything from the BD12XX.
My WDTV Live that I bought to replace all the media playing of my BD1255 (after buying actually to replace the media playing of my LE46B650) actually does export Networks Shares and has a DLNA Play-to functionality.
If you're looking into that sort of stuff, I think you better at have a look at the Popcorn Hour models.
