It looks like there is no standards out there at the moment, and everyone can name their releases as 1080p. But what is really an 1080p release that is the question, lets compare two releases...

Both are released as 1080p, the first you will notice is the file size. the next you will notice is the hight at 812 pixels of the first. So one of these is clearly not 1080p..
The HD resolution standards are:
704×480=480p (DVD)
1280x720=720p (HDReady)
1920x1080=1080p (HD)
You would think the releasers of these hd movies, would follow the standards but they dont. So if you for example get a 1280x500 and it says it is a 720p but it aint, its what i would call a upscaled dvd quality wise.
Is there anyone else here that are into HD releases, what is your toughts about this?
