Flashing light and Freeze after firmware 2.0 upgrade

I have 2 WD TV Live SMP units (one on each floor of my house).  I updated the firmware on both.  They were working for a day or two it seemed like after the firmare update.  However, now when I thur the units on, it seems to go to the menu screen and before I can navigate anywhere the unit’s power light starts to flash and the system freezes i.e. I can’t navigate anymore.

Any ideas and are others experiencing similar?  I did try to do a search on flashing light but wasn’t able to come up with anything.

If you wait long enough, it will probabyl come back to life.

But to avoid it, turn off the 3-hour auto-shutdown feature in SETTINGS / OPERATION menu.
