I think that you may be misinformed.

Blu-ray is a physical disk format for high definition video. Blu-ray is capable of 1080p, which is 1080 lines of progressive scan video. At the moment HD broadcasts are in 1080i, which is transmitted as two fields of 540 lines. A deinterlacing chip in the set-top box or the TV will convert this back into 1080p.

What this means is that in theory, Blu-ray is slightly higher quality than HD broadcasts, though you're unlikely to notice a lot of difference.

Yes, but I think the long term plan is to broadcast directly in 1080p. But
I may be wrong, I am not a specialist.

Pfft...too much technical stuff here for me.

All I know is it looks flippin amazing and yes...the BBC HD channels are probably the best. Also, the Nat Geo HD channels are pretty darn good!
