I am just here with an F.Y.I., a friend of mine owns the 82738 and he has had huge issues with the 3D DLP link. I am uncertain what glasses he got but they were a package deal with the TV, glasses and stand. He was unable to get 3D out of the TV so he called Mits. He was given the latest firmware but to no avail. He started to really put the screws to them and finally said fix it or I want a full refund. They sent out a rep and he found out that one must sit 6 feet away in order for the DLP linked glasses to work. Of course this gentleman has some money thus his living room is plenty large enough and the seating is many feet further away than 6 feet. He then proceeded to buy the adapter and circumvent the DLP all together by using the IR settings. This fixed the problem but after he spent several hundred more dollars. Again I do not know if this was the glasses but they were designed for DLP link or else they would not have worked at all. If someone has a better work around they may want to address this if it has not been already, good luck and happy configuring.
