So neither Oppo 93 or 95 can stream sacd or dvd-a iso's over a network. But it can play dvd-a iso's from an attached external hdd via usb?
With the proper firmware from last December or earlier, you can playback DVD-A, Blu-ray and DVD-V ISO's from an attached HDD. Unfortunately, if the firmware has been updated, there's no way to roll it back. ISO playback was removed at the request (demand?) of certain studios.
There actually is a way to stream both SACD and DVD-A ISO's to the 93/95 via DLNA using Foobar and the DVD-A and SACD plug-ins. The SACD ISO's are converted to PCM on-the-fly.
edit: I went back to read the earlier posts in the thread and this seems to have already been covered. Recent versions of the SACD plug-in have come a long way and give reasonably good results now. I don't experience any of the pauses and stuttering that earlier iterations caused.
