Here's the conceptual analogy that comes to mind with HD-DVD/Blue-Ray movie playback, let me know if this is correct (again, conceptually, not technically)-
1. 1080p- 60 full frames per second
2. 1080i- 60 'half' frames per second, for the sake of argument let's equate it to 30 frames per second
3. Blu-Ray or HD-DVD movie- 24 frames per second. Of course 24 FPS is less than either 30 or 60 FPS, so that's the rate limiting factor. And that's simply not going to change with the current formats.
Whether 1080p or 1080i, you are actually displaying more information than is in the original 24 FPS content (achieved via pull-down, etc.) Either way you are repeating frames of the original 24 FPS to display on a 1080p or 1080i screen.
