i know DTS on laserdiscs beats dvd, not sure about hd-dvd (blu-ray)
how good is laserdisc ac-3 vs dolby 5.1 on dvd and blu-ray.
and how good is pcm digital audio vs dolby 2.0/4.0 compressed?

joke of the day: how many super sayians does it take to screw in a lightbulb?

The source material and mastering matters but almost never studios mention of those. You can look at the facts below

Laserdisc:
Digital Tracks = PCM encoded at 16bit 44.1Khz sampling with 1.4mbps same as Redbook CD(music cd)
Analog Tracks = Probably same source FM modulated similar to FM radio or greater quality
AC-3/Dolby Digital= 384kbps with 5.1 discrete or 6.1 with back center matrixed into SR/SL
DTS= 1.4mbps with 5.1 discrete

DVD:
LPCM 2.0 & 5.1 with maximum of 24bit/96khz supported but rarely used
Dolby Digital/EX = 385kbps, 488kbps(mostly used) or 640kbps(legal limit but almost never used) with from 1.0 to 6.1(matrixed rear) implementation. 5.1 and 2.0 are mostly used.
DTS/ES/EX= 1.5mbps(about 25 titles) or 758kbps(mostly used) with 2.0 to 6.1 discrete. DTS EX is 6.1 with matrixed rear. DTS ES is 6.1 all discrete.
DTS 24bit/95khz was supported but never seen discs encoded with it beside demo discs.
Mpeg Surround was supported in region 2 with few available titles.

BD/Hd-DVD:
Dolby Digital/plus = 640kbps is legal limit and mostly used. DD Plus can support upto 7.1 and 3mbps(rarely used)
DTS= 1.5mbps(mostly used) or 758kbps DTS ES/EX/24bit/96khz also supported.
LPCM= upto 7.1 with variable bitrate sometitles average 3mbps peaking into 5mbps(uncompressed/lossless)
Dolby TrueHD = supports upto 7.1 with variable bitrate some titles average 3mbps(compressed/lossles)
DTS-HD = upto 3.0 mbps with 7.1(compressed/lossy)
DTS-HD MA= upto 7.1 with variable bitrate(compressed/lossless)

some dvd players have a dynamic range of 99db, but ld players go to 105db.

that's a bit confusing and a little too much for me.

get that player and then if you like the format it won't matter if it's this, that or the other thing.
focus on the player, you have posted 115 posts and still don't have a player.

you know more than you need to know, focus that time to get the extra money you need!!!!!!!!!!!

also what type of home audio system do you have?? you ask questions about 1 sub or 2 but do you own any now?

do you have speakers or will you just hook into the TV and use the TV speakers?
focus on these things, get the stuff you need.
i take it you have a TV already.
so 1st you need the player.
focus!

i agree with everything, you can get a really good mid range player to start out with for less than 100
and then upgrade.
it's just a place for him to post stuff and ask questions or to tell us that his mom will kill him if he gets a player.

Yeah, that was the part that confused me the most (well, actually this was the part that confused me the most). Why were we told these things? I really don't get it.

He found an old technology that has a forum and is able to communicate with others.
Even if he never gets a player he can post and talk all day long.

so i think that’s the deal, he just needs attention, or wants to fit in and can get it from the internet.
I’m sure he is on other sites under different names asking questions about other things.

I AM FOCUSING ON getting a player!
but i will save up for an elite, so far got 160 saved up (would have been 200, but i spent some money on taking my mom and 9 year old nephew to the show today).

it takes time.
