No. I have no interest in multi-channel audio.

HTTP. I don't think any other mode will work with the IPTV Recorder in
MythTV, but I could be wrong.

Yes and no. If you setup the scripts as listed on the wiki article at
https://www.mythtv.org/wiki/IPTV_Encoders_as_a_Capture_Device it should
be reasonable. I don't think you need to reset the encoder before you
tune a channel, so you could probably remove some of the startup delay.
In my case, I am doing something differnt - trying to record from
SlingTV on a Roku box, so "tuning" a channel involves shell scripts that
send "arrow" keys in the blind to the Roku UI once Sling TV is loaded.
It's kludgey, messy, and doesn't always work. I don't use it to watch
I may setup a separate Roku device outside of MythTV to use for "Live"
