The 1000s doesn't have a vformat button on the remote. Switching on/off the TV doesn't solve it. As I said that if I switch off the humax box and then back on it will come on at 576i, no amount of switching through inputs/HDMI swaps will fix this. Also if I cancel the recording whilst in this 'disabled' mode, one time it refused to cancel, the other time it let me cancel but then did not function properly and had to pull the plug to reboot. I actually don't think this is a sony fault, I think it is a humax fault. i phoned tech support and they said it might be a problem with the tuner. tempted to get a replacement box, but don't want to lose all my recordings.
