I just ripped the Blu-rays Mongol and Red Cliff into an MKV. Mongol is in Mongolian and Red Cliff is in Mandarin, but both have English subtitles. I ripped using Another EAC3to GUI Plus. I am playing back using Haali Media Splitter, ffdshow audio decoder, ffdshow subtitle filter, ffdshow video decoder, and Haali Video Renderer.
There are two English subtitle streams showing up for each movie. When I use Media Player Classic-Home Cinema to play back, I get the subtitles with no problems. When I use MC15, the subtitles will show up for a minute or two and then disappear. If I change streams, I might or might not have them again. If they disappear, I can select "No Subtitles" and I'll get a subtitle flash on the screen for a second.
What am I doing wrong? When I ripped the movies, I saved the separate subtitle, audio, and video files so I can remux if I need to. Any suggestions? Thanks.
