I for one am really looking forward to this only if it does not mess up my two 510's which have been very stable machines. If you have been with Dish for any length of time you should be familiar with their software issues. I am aware of the 522 which has NBR but also aware of the problems associated with it. I have wanted a 522 for a long time and have run a second line in the den in anticipation of getting one however being a existing customer and all the problems recently read about in getting one I may decide to get another 510 and run two of them to the same tv. (video 1&2). I would have twice the recording time and most of the advantages of a 522. I can also install the 510 and not have to take off from work or have some one I don't know come in my house to do something I can do half drunk and in my sleep.
