i have a basic confusing question about HD format on Blurays, DVDS,- concerning 360.

[JacksonLee]

hi. i'm a newcomer here, and i am totally confused.

Blu-ray is high definition, correct? it outputs 720-1080p
HD-DVD does the same thing.

however, DVDs output 480P. correct so far?

so how the 360 play HD games when the disks are DVDS? :?

HD is only available on BD and HDDVD, right?

Correct. Not so sure what went on with HD-DVD, but I think all blu-rays coming out now are 1080p. Some early ones came out in 1080i.

however, DVDs output 480P. correct so far?

Correct.

so how the 360 play HD games when the disks are DVDS? :?

Good question. I'm not sure. Maybe the console upscales to whatever setting you have it set for (720p, 1080i, or 1080p), or maybe there's a difference in the resolution between a movie recorded on a DVD and a game stored on a DVD. I've never really thought about it before, but now I'm curious. Hopefully someone will chime in with a definite answer to this one.

HD is only available on BD and HDDVD, right?

No. HD is 720p (or 768p), 1080i, or 1080p. HD programming in the first three resolutions listed is readily available through your cable compnay or satellite provider. Dish Network has some 1080p content on demand.

Games are not DVD-video You can put whatever data you want on a DVD disc.

Correct.

so, even if the DVD is duel-layered, it's impossible to have HD resolution?
(someone back b4 said that DVDs can have HD resolution... so im confused.

i don't understand what you're referring to. Games are not movies, obviously, but arn't the 360 games in DVD format? ( im pretty sure it is, while the ps3 games are in blu-ray)

that is why im confused. i understand that ps3 can have HD gaming cuz it has blu-ray, bu why the 360?
( or does the Blu-ray have nothing to do with HD gaming?)

I think what 42041 is saying is that even though the games are stored on a DVD disc, they are not in DVD format. The disc is just a disc and you're not locked into any particular format or resolution just because you store a file or application on it.

no, that is why they don't play when you put them in a normal DVD player. A DVD Or BD or CD is like a box, if something fits in the box trhen you can put it in the box. Beyond that you have music for CD and video for BD and DVD specs, these specs are so that they can play in the players. The 360 uses the DVD "disk" but the content is not DVD "video" it is 360 content. So it needs to respect the limitations of a 360.

DVD-video is a format which specifies the MPEG2 codec at 720x480 resolution. It has nothing to do with DVD data discs other than the fact that it's the same physical medium. A game disc can store code, graphics resources, video, sound, etc. The resolution the console renders has nothing to do with the optical format, you could program a simple 1080p game on a floppy disc if you so desired. You could even rip and recompress a Blu-Ray video stream to 8.5gb and burn 1080p video on a DVD disc, though obviously it'd be incompatible with blu-ray hardware (and won't look very good).

The movies are on DVD-Video discs and as 42041 states, these have specific specifications and limitations.

XBox 360 games are on DVD-Rom discs which is something else entirely.

Blu-ray Discs and HD DVDs can be 720i, 720p, 1080i, or 1080p.

The XBox 360 needs an HD DVD add-on drive to playback HD DVDs. However, the XBox is limited in its outputs:

- Using component video will allow games to display up to 1080p on televisions that support 1080p over component (mine does). DVDs will display at a maximum of 480p while HD DVDs and digital downloads will be displayed up to 1080i.

- Using either the VGA or HDMI connection, you will get up to 1080p for games & DVDs and up to 1080/24f for HD DVDs.

Toshiba pulled this crippled output mess with their HD DVD players: low-end models only offered 720p/1080i output regardless of connection used, high-end models offered 1080/24f over the HDMI connection.

Blu-ray Disc players and the Playstation 3 output in 1080/24f over HDMI regardless of player.

The limitation for the resolution is in the display used. IE: A 720p set will only display up to 720p, same goes for a 1080i set.

HD is available on Blu-ray Disc, HD DVD, digital downloads, Netflix Instant Streaming, Amazon Video on Demand, and Cable/Satellite broadcasts & Cable/Satellite Video on Demand.

Cable/Satellite broadcasts are up to 1080i output, while the Video on Demand offered by these providers have the choice to download a 1080/24f presentation.

Digital Downloads from Apple, Sony, Amazon Video on Demand, and Netflix Instant Streaming offer 720p HD.

Netflix Instant Streaming is not a guaranteed 720p presentation. The Netflix's movie server determines if your internet connection is fast enough to handle the video coming in.

Microsoft now offers 1080/24f video on demand but to take advantage for the full 1080/24f video, you have to use the VGA or HDMI connection as I stated earlier. Otherwise, the best quality video will be up to 1080i.
