When I turned my 721 off this morning the Record light came on and I thought that was odd cause I knew I didn't have anything set to record in the Morning so when I turned it back on it was taking the update , took about 5 min and then I wne into sys info to check and it was still L175 so I did a Power Reboot ( Hold in the Power Button for about 10 seconds) and after the reboot Proccess I went to sys info and it was at L177, Don't what features it adds or Improves ( Hopefully No Ill effects ) anyways as of a few Min ago the dish site still didn't have this S/w List on there . SO if anyone know whats this update is supose to be for , let us KNow !
