HD on pc games?

[The Stinger]

I was just wondering if someone could settle something for me.

With all the talk about blue ray and how High Def will take up too much space for a standard DVD9, I was wondering, how do they put pc games with high def on DVD9? Is it lots of compressing or can HD fit on a DVD9?

games arent solid video.......to be quite honest, its literally that simple.....video is a lot harder to compress than actual game data...that and...well, i guess the best way to describe this........games dont really access quite as much data as movies do (which is why, if you have a video game system, you will see that the laser isnt ALWAYS active (you can hear when its accessing the data) also, generally speaking, they compress the game data for games so that when it installs, it accesses a LOT of the data from there, then maybe movies...or maybe NOTHING AT ALL (except to check the files on the disc itself, as a copy protection) i guess the best way to describe it, is video is more "solid" data, i suppose? that and also most games dont have 1 and a half to 2 hours of ingame video and they are compressed with propritary codecs most of the time, as opposed to mpeg 2 (dvd) or mpeg 4 (HD DVD) that are more suited to compress CGI video...this also at the same time, explains why some CGI movies are on single layer dvd discs as movies and they look REALLY good........i hope that wasnt too confusing (its getting too late here for me to read what i actually typed)

I'm no expert butkeep in mind that the term HD has nothing to do with any compression applied. It has to do with the resolution of the video just like 720x480 is ntsc standard dvd
1280x720 is one of the HD standards. That's why many HD 16x 9 TVs are 1280 x 720 screen resolution.

Game data is compressed and in almost all cases requires an install and temp storage location for all data. Some data remains compressed on the disc and is uncompressed as needed into memory locations. As others have said, not alot of games have more than 20 minutes or so for video, so those HD Videos are taking up a tremendous amount of space that a full feature movie does.

It's a combination of compressed game data along with short video clips that keeps the size of game storage down.
