I have official confirmation that Engineering is doing testing at the moment to try and find a fix for the problem.
The testing is currently ongoing, but the speculation is that it is somehow due to HD channels added to 61.5 and 129.
So, if your setup happens to be workable if you disconnect your 721 from 61.5 and 129, then you can temporarily escape the effects by doing so.
