Ok peoples, need some help, I got a samsung 7000 series tv with a ht 6750 home theatre and my sky.

whats the best way to hook all this up.
currently I have sky connected to ht thru hdmi and ht to tv thru hdmi.

I can control the ht and tv using one remote, but the one remote wiil turn off ht and tv but will only turn one back on. if I use the the ht remote to turn on tv then press the "BD" buttom to turn on the ht it doesn't turn on to the sky input, instead it loads the digital in screen, and says I can hook up cable or satellite box using an optical cable...does sky allow for this kind of connectivity?
