OPPO 130D

I view the film and I speed up manually the subtitles of every languages on my OPPO 103D and nothing takes place, no subtitles nor of forced subtitles, before this worked correctly, on the contrary on POWER DVD 13 and VLC subtitles are well present.

Still same answer:

Software in the Oppo. There are "discussions" about it on other forums, and here as well. You have to manually turn them on each time it starts playing a file.

Your question is better asked in a forum where the Oppo is supported. No one here has control over the software in the Oppo.
