hi, newbie here. looking for very first HTIB for my toshiba 52hm94. This Yamaha YHT-760 looks nice for its features, support most formats, 5 disc dvd player included....but can't find any good review on it. Can anyone give me some feedback on it's performance? 1)is yamaha any good? didn't see much people discuss it here. 2)should i go for 6.1 or 7.1 system? 760 only support 5.1
