Sooner or later, someone at SD is going to have to handle scheduling
of their asymmetric tuners.  I curious how they're going to eventually
handle it.  For MythTV, having separate, virtual, channel numbers
would probably be an acceptable solution.

I believe Mediacodec on the Nvidia Shield, at least with MythTV,
handles is correctly.  I wasn't happy with the 1x deinterlacing done
by Handbrake when transcoding some 1080i, TV recordings to HEVC a
while back.  I eventually used ffmpeg to do the trancoding instead and
preserve the interlacing.  The results played fine for me.
