That's a "hidden hack" or a combination of features. Sync Playback to Display will use the display clock to time the video image to screen. While PT audio runs at wallclock (most of the time not the Display Clock), Sync Playback to Display would plain disable PT and output LPCM.

Though - as we did not want that SPDIF users with 2.0 pcm channels only, would loose surround sound, we go the Transcode path in that combination. So for your Sony TV that only supports 384 Kbit/s with the official API - you cannot output normal 640 Kbit/s AC3, right? Therefore this setting combination will decode it and reencode it to 384 Kbit/s AC3. Clever isn't it? (Without the Sync playback, no need to reencode and 640 Kbit/s would be output).

The difference between "goodpatched" and "probablyfinal" is the following:
- goodpatched had a more intrusive fix for the LiveTV issue, e.g. the opening of single decoders. This might cause a lot of issues and is not well tested and far too intrusive for Krypton
- probablyfinal instead tries to workaround that issue within MediaCodec itself without harming the complete architecture of all other OSses, only cause of Android shortcoming.

Any questions left?
