If they are monitoring this tread,They should get our wishlist for the future firmware upgrades.So,here is my short list:
1) Dolby True HD on HD DVD in 5.1
2) 1080P in 60Hz
3) Distance settings in Speaker settings
For number 3), I am not shure if that is possible,but for first and second,if Toshiba did it(number 2 in opposite direction), LG should do it as well.They are not small company without experience.
