Just started having a problem with my 722k when trying to access My Rentals. If I go into "All Movies" then "My Rentals", the message "server connection failure - receiver unable to connect to network server" box appears. Only choice I have is to click done and go out of the DVR menu. I have tested my WIFI connection and the DHCP test passes without error. Also I am able to search movies without problem indicating there must be a good connection to the Dish server. I do have 3 rentals in queue and was wondering if one of them is causing the problem, but I can see no way to get past the error box to delete them. Any help is appreciated.
