Yep, genuine 1950's interlacing technology :-)
The header has a flag to indicate interlaced. The resolution is reported
as 1920 x 540 with 1:1 pixel aspect ratio.
The header also has a flag to indicate progressive - not sure what you
are meant to do if both flags are set.
VLC gets it wrong (displays square pixel 1920x540). Microsoft gets it
wrong (displays square pixel 1920x540). LG TVs decode correctly.
Going to be a mess.
