Last week Thursday night, the DirecTV and OTA channels were not working at all. DirecTV had a message on the screen about knowing the channel was not working, the OTA channel just showed a "searching for singnal" message. Didn't last long, or at least didn't last long from when I noticed it.
KDSM had that message for awhile last night.
And watching part of the Cardinals/Vikings game was really jumpy.
