Next week at church we are having a yard sale. I have several old dish and directv receivers. I have the following dishplayer 7100,4000, and a 1000. Also have a few directv receivers all standard def. Are these receivers even worth selling . I called dish and tech more or less said just junk them.Since they are moving over the mpeg 4. I am assuming directv which will converting customers to mpeg4 from mpeg2 also. Just a thought if I installed the dishplayer and added to my acct. I would like to have another hd receiver for my hdtv upstairs. Would dish give me anything for the dishplayer toward upgrading to another hddvr?
