This item has become faulty in the last few weeks after working well for 2 months. The TV picture using HDMI output freezes or breaks up, and the sound is often out of sync with the picture. I have tried using my digital TV with its own aerial signal and this works fine, as does my old hard-disk recorder. I have checked the aerial signal strength and quality and this is good. I have tried resetting the recorder and replugging the HDMI cable but this has not corrected the problems with the HDMI output.
