Had it a few weeks I think. I can't get the thing to change channels to the right channel 100% of the time so sometimes it keeps recording the wrong dang thing. So I fiddled with the code..changed it to a previous one that worked slightly better..got everything set...and when I got out of all the menus the picture was going nuts being very pixellated and the live thing on the bottom right was stuck on..and the remote won't do anything other than turn the power on and off... What's going on?
