Just bought the Pioneer 530 and all seems OK apart from a couple of concerns. First, while setting it up and generally testing out some of the features there have been a couple of occasions when it seemed to lock up, nothing responded short of unplugging it at the mains. Does anyone have any experience of this, is this a known problem? Second, it has gone through the motions of downloading the EPG information a few times but no information seems to have been downloaded. I'm connected to a terrestrial aerial and have definitely left it in standby. How long should the initial download take? Thanks for any advice.
