Software was up to date...did a factory reset/software update on both TV and DTV stream box so will see how that goes.

The above did not work...still needed a reset a few hours later...what it does is lock on a jittery SD resolution and can't change channels, etc.

@gtsmith23 If you are still under warranty then I would contact Directv customer service about getting a replacement because if the box is still having this issue and you reset everything then that would lead me to believe that there is something wrong with the box.

Yep, I just requested a replacement box which is on the way, thanks!

You're welcome I hope your replacement works a lot better for you when you get it.

Same thing happening with a new stream box.  Ugh.  Weird thing is that it seems to only happen like once a day or a long time period between uses.

Do you have HDR turned off in the Dtv stream box settings?
