I have a 12TB disc with nearly every 3B BluRay Iso on it. All play fine on the oppo. I have been and always shall be an ISO guy even though it takes up a bit more space..
One issue with 3D titles (iso I try) with this player is related to foreign movies with subtitles. I see the subtitles are not displayed with the 3D depth which can be annoying. I also have an older Dune HD Solo 4K media player playing 3D isos and that player addresses this issue and displays 3D subtitles at proper depth. If anyone has a solution for this for M9702 please share ..
