Hi there I ordered a Panasonic TX-32LXD700 http://www.panasonic.co.uk/lcd-tv/tx-32lxd700/index.htm and I also ordered the Logitech Z-5500 5.1 speaker system.(5 speakers + sub) If I connect the TV to the Logitech speakers, will the sound be proper 5.1 surround? - and if it is - will it do this via BOTH the analog and the optical audio outputs on the TV? And if it's NOT proper surround sound, then what can I expect to hear from the Logitech speakers? Thanks!
