Most of the OTA HD content in the US is interlaced (1080i), with the
notable exception of FOX :-)
Some TVs are able to recognize interlaced content even though you're
supplying them with a non-interlaced video signal (e.g. 1920x1080 at
60Hz). The quality of the TV built-in de-interlacing may be worse (or
better) than VDPAU (which is very good with the advanced methods).
