What will be the native resolution of the video content of HD-DVD and Blu-Ray. I have seen many answers to that question all of them saying different things. Some say the native resolution differs upon the choice of the studio (720p, 1080i or 1080p) others say the discs will contain only one resolution (either 720p, 1080i or 1080p) but the disc players will be able to up- or down-convert to the desired resolution. I think the issue needs a clarification.
Can someone give a reference to an OFFICIAL information about this matter? An answer containing info about frame rate (24,30 or 60, or 24,25,50 in PAL countries) would also be great.
Thanks

All the answers you have heard are correct. The Offical Maximum for BD is 1080p, but Samsung has already stated that its first gen BD players won't be able to produce 1080p images. So in that example it is a hardware limitation. It was intetionally limited to 1080i to save some money.
Movie producers and directors have full control over what quality the movies will be recorded and presented at.
Most HDTVs don't display 1920x1080 pixels so any source of digital content is built capable of streaming several levels of resolution. The first blu-ray player by Samsung still includes Composite Video, S-Video, and Composite Video jacks for compatiblity with analog tvs. The Composite Video and S-video jacks are limited to 480i because of technical limitations. The Component Video Jacks are limited to 480p because of HDCP. The HDMI (HDCP) port is the only output capable of 720P, 1080i, or 1080p.

What I understand from your comment is the following:
Studios are free to choose between 720p, 1080i or 1080p for the content of the discs. Blu-ray or HD-DVD does not impose one of these formats.
Am I wrong?

Right. That would be like saying that all movies have to be made in wide screen since most are. They don't have the power to do that. There business is the storage medium.
As far as protection (features) and flexability, Blu-ray lets the movie studios decide that too. HD-DVD doesn't.

i remember reading HD-DVD could not play 1080p, but only 1080i or less.
But they all do sort of the same thing, and that is rearrange what you thought was real, and they remind you of the beauty of very simple things. You forget, because youre so busy going from a to z, that theres 24 letters in between... You turn on... tune in... and you drop out...

Quotes from The High Definition DVD FAQ...
BD:
Quote: 3.6 What resolution will the video on a movie BD be?
BD resolution will follow the standard HD resolution standards currently used for HDTV transmissions. This means, at least for the present, the maximum resolution will be 1080i/p, or 1920x1080 in either interlaced or Progressive format (progressive being the better, although not many displays can support 1080p, and even less can resolve or display the full 1080 lines - more information about the difference between interlaced/progressive video in section A.2). There is also 720p resolution (1280x720, progressive), which is the current native resolution of many home theatre displays, and also SD resolution support, similar to today's DVDs.
HD-DVD:
Quote: 4.6 What resolution will the video on a movie HD DVD be?
HD DVD resolution will follow the standard HD resolution standards currently used for HDTV transmissions. This means, at least for the present, the maximum resolution will be 1080i, or 1920x1080 in interlaced format only (progressive is better, although not many displays can support 1080p, and even less can resolve or display the full 1080 lines - more information in section A.2). There is also 720p resolution (1280x720, progressive), which is the current native resolution of many home theatre displays, and also SD resolution support, similar to today's DVDs.
The lack of 1080p support is something that even supporters of HD DVD are complaining about. Even if 1080p output is supported in the future, the actual movies are stored in 1080i format, so it will require a bit of de-interlacing to produce a Progressive picture, as opposed to BD's Progressive source.
