Hi all finally getting on the HD/Blu-ray wagon.Picking up my Sony HD tv on Saturday want a Blu-ray player to go with it.I've got a Yamaha 357 amp but it doesn't have hdmi,looking at the Sony BDP-S370 had a good review and the price is very good at the moment.The only problem is it doesn't have multi-channel out to use 5.1 audio for blu-ray sound.Been told at sony centre to use optical lead for sound.Is it really worth shelling out an extra £150 for a Panasonic DMP-BD85 for 8ch output or will an optical lead on the sony be more cost effective.Don't really want to go over the £200 mark. All info appreciated. Many Thanks. Alan.
