I had a Sanyo Z2 projector which had issues with the DVI output of the 530. The Z2 was know to have HDCP issues however. Later, when I upgraded to a Sanyo Z4, I had no problems at all using a DVI-HDMI cable running to a HDMI Switch. I know others with different front projectors...Sony, that don't have issues. I'm surprised it's giving you issues.
Have you tried different cables or adapters? I know I had a monoprice adapter that didn't work....had to use a Source for Circuit city (radio shack) adapter. Try a different DVI-hdmi cable...This has helped others in the past.
Sometimes to get the picture to sync properly I have to turn the 530 off and on.
As for using Component...there are proper RG6 F-type ends to RCA end adapters. I used them but now I strictly use HDMI. I can't really say the picture was inferior with the component cables though.
