De-interlacing demystified
This site is targeted towards people looking for information on video compression, but their information on de-interlacing, how it works and the various challenges faced can give you a lot of information on what your TV or media player is doing when upconverting content. If you can't understand why some people get so up in arms over the 1080p-or-not debate, or why SD content can look so bad on your brand new HDTV, take a look and be educated. There are a lot of ways to get around resizing and upconverting content, and some are better than others (blending fields, adaptive, bob, bob and weave or progressive scan, motion compensation or motion adaptive just to name a few).[Via DV Guru]

No. Way. I was just looking at this site not even a week ago. Really, really useful info in there.

The whole 1080i vs. 1080p is a sham for film-based content. You can recover the complete 1080p24 picture from a 1080i60 output, as long as the flags are set correct. The one catch is if there was any vertical filtering used. It has been posted that HD DVDs do not have any vertical filtering, since its not really needed for HD.
There is one disadvantage having a device that outputs 1080p60. Your stuck with the 24>>60 judder, and since its progressive you can't get back to 24fps (or 48hz).
Once true 1080p60 or higher cameras become the norm (for HD video) , this will be an issue. One thing that might speed this up is the impending release of the "Red" camera, but thats a whole different story :)
