Dish 921 HDTV software upgrade issues?

If you have one of the older verison Dish 921 HDTV receivers, be wary of the next software upgrade. Dish just upgraded the software version from L2.15 to L2.16 and apparently has caused quite a ruckus. It appears that this upgrade is causing issues with the OTA channels and guide.

This forum has dozens of recent comments on the situation. Apparently many Dish customers that aren't local channel subscribers have lost their OTA local channels and guide information. Some of the forum members are claiming this is Dish's method to push local channel subscription for additional revenue. Until this sorts itself out, we'll stick to watching reruns off of our PVR.
