 The biggest challenge when recording from an Android TV Box (video streaming hardware) is to record video and surround sound in sync. I tried several ways of doing this and found one which allows me to do it in one recording without too expensive hardware. I have not found a video capture card on the market which allows to record a protected video stream or multi-channel surround sound.\\ The biggest challenge when recording from an Android TV Box (video streaming hardware) is to record video and surround sound in sync.

-  * Disc Player: 1000 USD (you need to find a premium player or another device with HDMI passthrough and analog surround audio outputs). Instead of a Disc Player you can utilitze any 5.1 pre-amplifier which supports an audio codec currently used by //Netflix//, //Disney+//, //Amazon Prime//, //HBO Go//, etc. If you use a pre-amplifier with variable output volume make sure you adjust the volume so you don't need to post-process amplification to it. Note that not every 5.1 pre-amplifier works, only one which supports the audio codec in the source stream.+  * AV Device: 1000 USD (you need to find a premium player or another device with HDMI passthrough and analog surround audio outputs).

 +  * Video Capture: 300 USD
   * Multi-channel USB audio interface: 300 USD (with 6 or 8 analog inputs). If you don't have one or do not want to buy one you can record the 6 channels in 3 stereo pairs and then sync the audio with Audacity. 3 stereo pairs means you need to record the stream 3 times, each time you connect a different pair of analog output to the analog stereo input of the Video Capture card (e.g. L/R, C/LFE, SL/SR).   * Multi-channel USB audio interface: 300 USD (with 6 or 8 analog inputs).

 +==== Notes on the Splitter ====
 +  * I purchased 3 splitters, only one of them works
 +  * Check that the splitter is EDID compatible
 +  * You need to make sure the HDMI master output of the splitter is connected to the AV Device and not to the TV, otherwise the Media Player apps see a device with 2 channels only. My splitter has a switch to set either of the HDMI outputs as master.
