HR10-250 Won't get single digit locals
I just purchased a replacement DirecTV HR10-250. It has upgraded to the latest software (6.4a) and will get and show info on all local channels. However when I try to watch any of the single digit local channels (I don't have HD service) I can see the channel banner & info but there is a blank screen behind it. I've spent over 3 hours with DirecTV support to no avail. Any ideas? If push comes to shove, could I just swap the old hard drive from my old HR10-250 with the new one? The old system worked fine except for a bad tuner on one side. If so, are there any specifics to making the swap? I appreciate any help.
