1080i VS 1080p

[Frode]

Let me see if I can simplify this a bit:

1080i crt = use 1080i
1080p LCD/plasma/DLP etc = use 1080p
Everything else HD = use 720P

That will ensure you get the best possible quality. Even if you have a 1366x768 plasma/LCD, stick to 720P because the display most likely won't be able to properly deinterlace 1080i.
