Just realised there is only one SD H264 Channel. I will have to experiment to see if Kodi remembers if you "Stretch" to 16:9 for a particular Channel.

Creating audio stream (codec id: 86019, channels: 2, sample rate: 48000, pass-through)

Been Cherry picking in Owersun's and Koying's SPMC Orchard today and have AC3 Audio passthrough working and some improvements as well for DVD playback with an updated LibreELEC version from HERE

I have not tested DTS Audio Passthrough.

Not sure but I believe I have Yadif Software deinterlacing working, onscreen text still appears a bit blocky but I no longer need to Disable de-interlacing for 25fps movie DVD Rips.

I can disable Hardware acceleration and the only TV Channels I have issues Software deinterlacing are 1920x1080i H264 ones. Not enough CPU Ponies.
Still not as good as video quality when using AML Motion Adaptive Hardware deinterlacing, but good enough for DVD's.

I will be interested to see of Noggin's Doco and Music DVD Rips play properly now ?

Shout when it's available to download and I'll give it a test.

Interesting you say AML deinterlacing is Motion Adaptive. Will look a bit harder, but it looked better than MA to me. It certainly didn't look like a global MA, I guess it could be block-based MA (which may be what Intel do as well).
