1 thing I noticed right off the bat is this,where you did the 5.1 upmix on the TV scenes you should of boosted the speech volume,it is waaaay lower than the normal scenes,very drastic,especially on a high end sound system(so for me,this is not good,but that is me,maybe noone else cares),and I want to look at the picture more,it does look a little soft,but I will look more into that tomorrow.
But hey,you did the work and that's cool,but the sound level problem alone is enough to keep me on the original sound(not the 5.1),hopefully no level drops there,I have not checked that out yet,will tomorrow.
The 4:3 menu's are pretty cool,why not 16:9 menu's?
