Page 1 of Tevion HT95____ How to link up to Xbox Dolby Surround feature?

I`ve not long ago purchased this Tevion HT95 from ALDI and have been very pleased with its DVD playback picture and sound quality. :)

But I want to use my Xboxs` Dolby Surround feature and play the sound through my new Tevion.
I`ve tried connecting a double end SCART cable to my TV in one SCART socket on the TV, then an optical cable from the Xbox to the Tevion with another seperate SCART socket used up to connect the Xbox to the TV but when I turn on the Xbox the Tevion does nothing, only displaying `No Disc` for the DVD function.

How do I get the Tevion to output the Xbox`s sound?

Can I connect the Xbox and Tevion up the TV at the same time or am I stuck with a sound sys I can only use with the TV?

Any help will be appreciated, I aint got the slightest beyond maybe connecting the Tevion & Xbox through the same SCART socket on the TV, would that work?

HELP! :/ :/
