That is what I was starting to wonder as well, if this is being caused by lnb drift. Did they have many issues with the DP twin lnb's for lnb drift?
I had the drift issue affect my 721 a number of months ago. Dish came out and replaced both LNBs on my dish and it cleared that issue up at the time.
The issue had been ongoing, to the point that the original head of the product development team for the 721 called to discuss it. He said the 721s were more sensitive to the drift than newer receivers. (He's the one that identified it as a drift issue - the Dish techs had been to my house repeatedly, unable to correct the loss of signal, until they did what he said and replaced the LNBs.)
I'm not saying this is not a new drift issue, just adding data...
So I take it that if the 721 receivers do not have the drift software then the legacy receivers will not have this software either?
I am not well versed on LNB drift, but it seems unlikely that every 721 owner involved in this thread developed LNB drift problems simultaneously. Of course maybe I know even less than I think and it is possible. Please correct me if I have my head up my heinie.
Just to reiterate, as I said several pages back, I am experiencing no issues whatsoever with my 721 at this point. It seems to have healed itself.

I just checked my setup. On my 721, I have a superdish 105 going to a DP34, on the all the even transponters/spots on 110, I have 0 signal strength flashing to 60-80 back to 0.
I also have a 7200+ on a legency twin with good signal on the evens.
What is your setup?
That flashing SS caused by bad sat tuner chip - same reason exist for 501...510 PVRs, the model share same chip and same problem. I saw reports when ppl 'borrow' the chips from 501 or other (301 ?) receivers and fix the problem in 721.
Oh, now the LOF drift taken into that SS screen.
My experience with such problems in past shows:the reason was 100% of the chip ( not a card !) failure.

The early 721s had bad tuner cards... the chips are on the card... they would do this same signal strength jumping back and forth.
Different problems but same outcome on the Point Dish Signal Strength Screen... because the tuner chip cannot lock on the signal.
Actually it is nor a card, but sub PCB, because it does not sit in a slot and cannot be re removed without desoldering. Man, I'm sound to technical, but your terminology is so 'internal' - we are live in other 'PCB' world.

Hardware is not my thing.
Can anyone confirm the 301? My second receiver is my original 301. If it can be verified as a tuner-chip donor, I'll make sure it never leaves the house!
