I currently have a 5.1 home theater system but have noticed that the movie theater has 12.1 is there a chance to upgrade with the components i have? or do i need a new receiver?

you have a little time to save up. even the very best DVD's you can buy right now only have 6.1 channels' worth of signal on them. you'll be best served hanging on to what you have now and giving the industry another year or year and a half to see if more advanced formats hit the streets.

How do you figure the theatre has 12.1 channels ?

From the last time I have checked Sony SDDS is 9.2 discrete, there also ways of matrix decoding other channels from this to equate to 12.2

For Instance working front most to back and left to right

Left Center
Right Center

Left Matrix
Right Matrix
Left Rear

Left Matrix 2
Right Matrix 2
Left Surround Back
Right Surround Back
Then there would be two LFE Channels behind the screen

I beg to differ. Im not sure where you received your info but its not accurate. SDDS is only capable of 7.1 channels. There is no such thing as matrixed channels in SDDS.

The other thing to note is SDDS is going to be a dead format in a few years. Sony no longer supports this equipment and the only reason the format is still on film are the contracts that where signed by some major theatre circuits.
