You will only see the current and next program until the guide fills in. Usually you can force a fill-in by moving the select right hours (arrow) or days (skip). It may require going nearly the 8-day out. This will be only a little faster than a switch check but you may be able to continue recording although the current tuner is used to fetch the guide so you may need to swap in single mode, untried.
To get the guide to download you can press 999 Browse in the guide. It will force the guide to download. If it does not work then the current guide it downloaded. This was told to me by a Dish Network Tech Support. It should work on all receivers. I have 2 VIP622's and 2 VIP612's and it work for all of them when I get INFO NOT Available. It is faster than going to the menu and doing a check switch every time
My 722 has had the same problem a few times in the last couple of weeks. Each time had to do a check switch to get it to download manually. Has there been another software download or something causing glitches?
