Hi i've just got a ps3 from VG+ and the screen flickers using either of these cables, is my ps3 buggered? can anyone help? I've tried the cable with a ps2 and no problem so i know it's not the cable.

Does it do the same over HDMI?

I don't know I haven't got a HDMI port to check it.

When I tried to set my component up there was this off putting ghost effect to the text and stuff. Plugged the HDMI in and it was spot on. Marvelous picture quality.
