What will the picture quality of a HD DVD 1080p movie played in a 1080i

720p

Very Little difference in the performance to be fair.

Unless your really going to look closely at the picture it is very difficult to see the difference between 1080i and 1080p.

The blacks may be a tiny bit more black etc. Both are high definition. It's just that 1080p is a little bit more HD.

Nothing ot worry about.

It all depends on the deinterlacer in the TV. A poor deinterlacer could cause anomalies when it combines the odd and even interlaced frames.

1080p will look crisper and cleaner but it would be very hard to tell the difference when sitting at normal seating positions especially on a smaller TV (ie: 40"). The artifacts or anomalies would be more apparent on a very large screen (ie: 100" projected image) or if you were only a few feet away from the screen.
