720p50 or even 720p60 would give superior motion with in practise better
vertical resolution than 1080i. It would better to let the video encoder
lose data in a controlled way than rudely alternating between two 540
line fields with interlaced video. Also now when carbon footprint
matters it's insane to double every set top box / HDTV power consumption
at recipient side for doing magical motion vectors based tricks in
trying to restore the 1080 line image.

Recorded from Anixe HD yesterday.

At the moment
VIDEO: [H264] 1280x720 0bpp 50.000 fps 0.0 kbps ( 0.0 kbyte/s)
Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family
Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264)
Opening audio decoder: [mp3lib] MPEG layer-2, layer-3
AUDIO: 48000 Hz, 2 ch, s16le, 256.0 kbit/16.67% (ratio: 32000->192000)
Selected audio codec: [mp3] afm: mp3lib (mp3lib MPEG layer-2, layer-3)
AO: [oss] 48000Hz 2ch s16le (2 bytes per sample)
But that was an old B/W film so not real HD content.
