I haven't checked mine yet, I had problems last night with my 721 it seems that I left it unplugged for to long and it forgot its remote address and lost its switch configuration.
It was making me mad because it wasn't responding to any buttons I was pressing on my remote. The sys info button on the 721 was not doing anything as well.
When I would boot it It would all go fine, the Dish Logo would come up and it would validate the hard drive, then it would say "Aquiring Satellite Signal" then that screen would go blank after 10 seconds, then it was just a black screen.
After a few minutes of going through everything I reset the remote back to address 1, thats when I could press the menu buttons and everything else.
After a check switch I was in business again.
I unplugged it because on Monday night it started pixeling up once every min or so, and sometimes after the screen would pixel up it would breifly say Aquiring Signal on the screen.
I checked my signals and they were good. And none of my other receivers in the house were having problems.
Once it was all reset the problem did go away.
Anyways because of this big reset I didn't check my guide because I figured it had to download it again.
I don't have a problem with a 7 day guide. 9 was nice, but I think a 7 day guide was all that was promised for the 721.
Plus dont forget E*8 is moving in soon so they are doing some shuffling at 110 so I would expect some slight guide problems over the next week or so.
