I have some movies that have foreign parts, and have downloaded and added the forced subs into Mezzmo. I have it set to burn the subtitles into the video on devices that don't support streaming the subs.

I have been streaming to my PS4, using the device profile I was sent via e-mail on June 19th. It has been working wonderfully, and all of my files have been playing without issue.

However, I noticed yesterday that after downloading the subs for a file, it wasn't able to be fast-forwarded anymore. I looked at the server, and it was transcoding the file in order to burn in the subs, so I assumed the fast-forward issue was just because it was currently being transcoded. However, I played it again today, and it is still not possible to fast-forward or rewind. The subs burned in fine, and the transcoding is done, so I'm not sure what the issue is. I switched the server to play the original file for the PS4, and fast-forward worked fine again.

Any ideas?
