I was wondering which (if any) of the following upgrades would improve the image quality fcoming rom my Z2 Projector... it's very good but would like to know just how good it could be... 1. Better component cables as I am currently using a basic (cheap) component cable 2. A better DVD player - possibly with a DVI output. I am currently using a Panasonic DV563 player and component cables 3. A line doubler I also have a Yamaha RXV 1400 Receiver and an Xbox and nan SA 8100 PVR with regular cable. Thanks to all for any thoughts and recommendations.
