They say that the memory is the first thing to go. :)

What you may not realize is that your 722 is performing a daily reboot anyway without you know it. And for deceptive reasons.

In Menu 8, 4, (a user preference) you can set for a time to download new Guide Data information (I think the default time is 3:00 am). Dish added this functionality because so many people were not putting their receiver in standby mode each day, and the Guide Data would get stale. The only time the receiver is allowed to download new Giude Data is when you're not watching something. So Dish put in this function to automatically force standby each 24 hour.

If you are watching something when this function activates, it brings up a dialog to either quite watching what you're watching, or update the Guide Data. You can't do both at the same time. But if you change the "update" to sometime to which to can daily "cancel" and prevent this functional from happening (and you still put the receiver in standby each 24 hours), the Guide Data still get updated properly. This "update" preference is really an engineering dogde around a deeper issue.

What most folks don't realize is that after the Menu 8, 4 function updates the Guide Data, the receiver will do a complete reboot; just as if you had done a front panel reset. This daily reboot masks the reboots we use to have to do for those instability problems that would accumulate over time. These are the kinds of software errors that slowly eat up resources (like RAM memory) until the firmware starts getting internal errors and things start to go haywire. Dish is either not skilled enough, or too lazy fix these software problem; and instead added this "hack" as a work-around. This is a very old "trick" in the embedded software world to make less stable systems "appear" more stable.

If no one believes me, try this experiment. As I said above, change the Menu 8, 4 function "update" time to sometime during the day when you can cancel it every time it comes up, but always put the receiver in standby each night to still get the Guide Data updated. Within a week or two your receiver WILL start acting very goofy, and will eventually require a front panel reset; or will spontaneously reboot by itself. It takes some time to demonstrate, but its very repeatable.

I've done this experiment many times just to test whether Dish was "really" making the 722 more stable with each firmware update. And it's true that the amount of time it takes for the system to destablize has gotten longer over that last couple of years (week or two instead of day or two). So Dish is getting slightly better, But don't let the "appearences" of less front panel resets deceive you into thinking that the 722's firmware is now incredibly stable; its not. Dish has just made sure that most of us don't see it.
