I've had my Pioneer 530H since June and it's worked fine, but in the past few weeks, when it records from GuidePlus, it's no longer changing the channel automatically on my Sky Digital box. The G-link cable, GuidePlus downloads and SCART connections have all been checked and are working fine. This problem only occurs when the Pioneer box is coming out of 'standby' to record. I've called Pioneer, they've not been able to help. Similar problem to the one described here Any ideas?
