Have forced subtitles to be direct render to video on all services, not just a few!

When you say "direct render to video" I think of "burned into the video" and can't be switched off.
StreamFab downloads the Video track, audio track and subtitles from the streaming services in the way the streaming services have them available.
I'm not aware of any services where StreamFab renders the subtitles into the video. Every case I've seen where subtitles are in the video (rather than a separate track in the download that can be toggled on/off) its because that is how the file was available from the provider.
To render the subs into the video would mean to do a full re-encode of the entire video stream. Doing that, and including a step to burn the subs into the video (so they can not be toggled off) would add time over and above all other processes done during download, how much would depend on your GPU/CPU.
But If you mean to just include subs in the download, in a way that the sub can be toggled on/off by the player.. that can be done now Settings -> VIP Services -> Subtitle Format (select Remux into file).
