BTW, I did get two emails from DirecTV with different procedures. 11:21MST and 12:11MST.
First one:
Attention all Dealer Partners: The following HD/DVR model receivers are currently experiencing system lock up.

Affected models: HR20-100 & HR20-700 / HR21/22/23 + R22

Please note: A simple, 30 second process will restore functionality to your
customers’ hardware.

Resolution:
Complete a red button reset.
Wait for video and if video appears, issue is resolved. If you receive a grey screen, go to Step (3).
If you experience a grey screen for more than 3 minutes, complete another
red button reset.

This should resolve the system lock up and programming should return.
Our Engineering Department is aware and investigating the issue. We will update you with new information as necessary.

Thank you,

DIRECTV

And second one:

Effective today at 12:50pm MT (2:50pm ET) DIRECTV will be forcing all affected receivers to RESET. This will clear guide data and will restore normal functions and services to impacted customers with the following receivers: HR20-100 & HR20-700 / HR21 / HR22 / HR23 / R22.

Customers that have completed RESETs earlier will once again receive a RESET. Please advise customers not to interrupt the RESET process.

Thank you,

DIRECTV


So it seems that they did have two types of issues.

BTW, I do not know what kind of advanced, super hyper DVRs they're running, because the ones that I reset, take WAAAYYYYY longer to reset than the 30seconds they're quoting.
