I have had the vertical hold problem for over 6 months. I called phone support and couldn't get it resolved. It was 3 sources: 1-VCR using composite inputs, 2-vs/maxx handheld self contained game console using composite, 3-Jakks Spongebob self contained game console using composite. Didn't matter what composite input. The 1070 is connected using component into the tv (sony HDTV)

Interestingly, when I put it into the front composite inputs of my toshiba dvd player, which then goes component into the 1070 - behold, no problem.

Other issues I am having - the "no audio" issue discussed elsewhere, occasional power toggle on my universal remote not working (could be a million things).
