In which build exactly? I'd like to test it.
I've been using kszaq's S905X Krypton builds, and all of them are/have been silky smooth.
I've tried both Krypton and Leia builds for the S912 and still have the stutter from srt subs appearing.
I will keep an eye out as I have one of the suspected "dodgy" eMMC Mecools (I've installed to internal, and 3 or 4 updates later it's still going strong........ so far), which I'd like to upgrade from to the S912 permanently.
Being my first post, I'd also like to say a big thanks to all the Amlogic dev team for making this rocking little box sing - Cheers gents!
