After it has been on for a few hours it seems to get clogged up. Could be something to do with memory usage. The easiest thing to do is cycle it on/off from the back and it should be good to go again. Also turning it off overnight seems to delay the problem. It seems to be good for 8 hours or so before it runs into problems.
370 is still working. It doesnt matter how long it is turned off for. Turning it off just gives you a fresh start when you start again the next day. It would be the same if you restarted it when you start watching.
You will usually get problems with all receivers at autoroll time. The last ECM is about DN ID 0101 keys and autorolls and all receiver fixes are slightly deficient. You should turn off switch at back and on after a minute to get rid of the problem. The last key change was at about midnight EST.
STEPS TO TRY TO FIX THIS ISSUE. 1- load the factory bin 2- load the current bin 3- check your settings in antenna setup turn off rear switch for about 2 minutes then turn on.
