Sorry my pal but that is the basis of Dolby Surround encoding : to take 4 indepedant channels and matrix them into the 2 stereo channels. And they are completly dematrixed and restored by the DPL decoder. Go there to see how it's done.
This is real surround because you can have completly different sound on rear channel (for instance music) while other three receive the voices.

It's true surround, and is like this since 25 years.[/b]

So does anyone know why my receiver, and also my dad's receiver don't like Dual Channel at all?
Is there some link, where I can download samples, which are properly made for Dual Channel and Stereo?

removing doubts Jell

your receiver don't like dual channel or surround 2 ?
did you try encode using dual channel with "surround(alone)" ?

so the mp2 file will be 2 channels but it will have surround sound within it?
will this work if i have a normal amplifier connected to the front output from the dvd player and another normal amplifier connected to the rear output, or does it need a special surround sound amplifier?

i have the same like you Bilal,
one Akai AA-A3s(Japan) and one Polivox AP-800(Brasil)
4 big speakers with piezeletric tweeters (Philips) that don't "hiss"
and some more bla,bla,blas....very cool and clean!
got good efects.

but for true surround you need a
"real" prologic receiver (amplifier)

yeah,"some" cool effects.


little hint:
remember,don't encode with too loud volume(normalize at 98%)
the volume is for the amplifier(receiver) not for the source.
this will encrease the quality and give less distorctions.
normalize turn the
low loud
and
loud low...
it means, encrease the low and decrease the high volume
changing the dinamic "impression" of the real sound
and sometimes is dangerous for quality!
listen the cds of "megadeth"...cool musics(i like) but
too loud and "unclear" knocking on the door of "scratch",
in the headphones is better than speakers.
the reason is the high impedance of the headphones that
decrease the volume and turn the sound a bit clear!

hey Bilal,i "talk" too much and it's only my oppinion!

thanks jorel for the ideas, this would have probably taken you a while to figure out so thanks for sharing it, and even if you talk to much it's good quality stuff

Bilal
Nothing special into the amplifier, but you must have a Dolby Prologic Decoder before the amplifier.
In AV amplifier, the decoder is already included, but you if you want you can buy separate decoder and add up to 4 amplifiers, one per channel.

That's the same for DPL2 or DTS.

i didn't have time to try it in the weekend as i went on a ski trip but i am encoding ocean's 11 now, already finished the audio using head3ache, i had to run ac3 fixer over it which fixed the head3ache problem, i have dolby prologic in my dvd player so i'll see how it goes when i get back home.
thanks for your help everyone.

Bilal, where did you find this ac3 fixer program? I don't know why but I often run into problems with headac3he crapping out on me mid-conversion. I usually find turning off 2-pass fixes it with minimal time difference. Maybe it's because I've always been ripping ac3 from dvd2avi? Maybe I'll try smartripper next time,

i found it in the tools menu in dvdrhelp.com it's called ac3fix here's the exact site for it:
http://www.digital-digest.com/dvd/do....html#ac3utils

i used smartripper and ripped the movie twice but it still gave me errors in ac3 file so this little program is good
