Thanks for the docs on that. It would indeed seem that the video file is identical in raw form and as it is indexed on the disks. Therefore your theory that only the players output is affecting the image quality difference, at least on the tested title from your source confirm. I don't have two computer drives to compare file size. My only information was observation of the image on scree.
Re HP latest release. I just saw the HD DVD version this week and it was much softer than the 300 image. The HP on BluRay (rental)has been checked out. If they are close, the only way to see the difference is with both where I can switch back and forth.
Keep in mind that my main reason to look at 300 was due to an award given for best image quality using that title. I have no intention in doing a scientific study of all titles on both formats using double blind methods. They are what they are and I watch and enjoy the formats for the content and story, knowing I have the best possible home theater format to see these works. I'm not interested in any agenda of one format vs. the other. There are enough pros and cons on both for people to make up their own case.
For most people here, offering an opinion that favors BluRay will piss off the HD DVD crowd and one that favors HD DVD will piss off the BluRay crowd. I'm in a different camp. I just want to enjoy the widest variety of titles in HDTV. That requires both formats and I will use them as necessary. Therefore I will piss off both camps at different times. Frankly I don't care. I'm more interested in finding the truth than giving free fanboy support for different companies or insulting members of the forum because they have a different opinion than my own. I'll just resort to insults when someone asks for it by acting immature and childish. If the insults are really childish, I won't even respond.
In another
thread, I announced another discovery supporting my BluRay player. It handles SD DVD's better than the Toshiba A30. Out of habit I was using the Toshiba for my SD DVD playback but as of last evening's discovery, I am switching to the Samsung player.
