Ick!!!!  I was just reading the thread over on silicondust:
I cannot believe that some stations are generating interlaced HEVC! I did
not add support for that when I added the HEVC decoding to MythTV. The HEVC
spec says that support for interlacing is an extension to the spec and most
people should not have to worry about it. Interlacing should be dead!
