Wanted to know about the Differences

Heay guys. M kinda new to this but i wanted to know about the difference between the following:

1. Movie 1080i
2. Movie 1080p
3. Movie 720p
4. Blueray
5. HD-DVD

I just wanted to know which would be the best to download and what would be the requirements to burn and watch them.

I normally download DVD-R but yesterday i was with my friend watching a movie, but before that it gave me an option to choose which sound would i need.(This is the first time i have seen an option of DTS sound) And when the movie started i was shocked :Owith the quality of the sound(the sound was really incredible).It was a DVD movie but had an option for DTS sound.
So i just want to know which of the following options can i use.
1. Movie 1080i
2. Movie 1080p
3. Movie 720p
4. Blueray
5. HD-DVD
and what should be the requirements do i need after downloading them. what software, CD-Drive, and what type of CD do i have to use to get these. A help would be appreciated.

First off all hd stuff is ripped from Blu-ray. So the ultimate would be to dl the actual blu-ray. For that you'd need a blu ray burner and blank disks which would cost you an arm and a leg.

here is a cutandpaste re the formats
There are two main flavors of high definition TV, 1080i (the i is for interlaced) and 720p (p for progressive). 1080i offers the most pixels, with a matrix of 1920x1080 pixels, while 720p has fewer pixels at 1280x720 pixels. However, the difference is made up with the frame rate, which is only 30 frames per second with 1080i, but is double that with 720p, at 60 frames per second. The total pixels displayed per second is actually very similar, with 720p offering 55 million pixels per second, while 1080 is slightly higher at 62 million pixels per second.

What does all that mean? It all depends on the type of TV you watch. 720p is better at showing pictures with plenty of motion, since the higher frame rate helps smooth any quick motion on the screen - this is better for sports or action movies. 1080i offers more detail, which is for movies with lots of images or panoramas.

The best of all is the 1080p option. It offers the best of both world, 60 frames per second at 1920 x 1080 pixels. The toal bandwidth is 124 million pixels per second, double that of 1080i. It can display any HDTV signal without any downconverting. 720p signals are upconverted, while 1080i signals only require some gently "de-interlacing" to work properly. 1080p is the perferred option is possible - its backwards compatible with all old formats, and is ready for upcoming high definition discs.

None of this has anything to do with audio, i know but if you're burning actual blu rays then it should have the best audio available.
cheers

thanks a lot for reply. so 1080p is the best option for sound and screen resolution. so is 1080p is blue ray or is it better to download blue ray formats.

yes

Thanks for the clear explanation John ;)

First of all you need to describe your setup (TV, audio, player).
For example if you using a simple 5:1 sound system there is no need to download a dts movie.

tv, i have full HD
and i am willing to buy new sound system support dts sound and blue ray player

Do you have your fullHD tv connected to your computer and play up your movies from there, or are you using a stand-alone player? As you may know, the formats you are asking about here is not compatible with a DVD player, so unless you play them from your computer you will need some other equipment, for example a streamer. I'm also fairly certain that bluray-players aren't compatible with the x264 codec these rips are encoded with (please correct me if i'm wrong).

Anyways.. fullHD means is native 1080p, so i would go for that (as long as your computer is powerful enough to decode it, or you have the appropriate equipment, that is)

EDIT: I re-read your post and noticed that you want to burn them. So i repeat again, if your watching them on a DVD-player, you can't play these formats. You will need to re-encode them to mpeg2. This is pointless since you will end up with dvd quality anyways. On the other hand, if you have a blueray burner and player you can download truehd rips or convert the x264s (if necessary, see above)
