I have 2 811's and just got my P 330 software a few days ago and now my guide is all messed up it says no info on most of the channels, i reset boxs and its ok for about a hour and then it comes back i never had any problems with my P 289 software (DISH GET IT TOGETHER OR LEAVE WELL ENOUGH ALONE) so ill just have to wait till the next update comes out and see what happens and im turning off my updates.
