I have a Mitsubishi HC1500 and I hooked it up to my laptop to play on my projector. I'm using the RGB (D-sub 15-pin) connector between the two.
My computer is an HP Pavillion zv5000 Pentium 4, 3GHz with 640MB of RAM and ATI Mobility Radeon 9000/9100 IGP (what ever that is). I'm guessing its a video card.

I try to watch a movie or Youtube videos through the Mitsubishi projector and the picture is quite jerky. It will become smooth then jumpy or jerky again.

What is the issue? I'm thinking that I need to upgrade something on my laptop. Maybe RAM or video card.

Any suggestions?

Thanks.

It only happens when I hook my pc to the projector. The pc work fine by itself.

If I understand your questions correctly, my labtop runs at 1280x800 pixels and the front projector is a 720p DLP.
I hope I answered it correctly.

To answer Marshall's question, both the PJ and the PC run the same video at the same time. When the video on the PJ gets choppy, I look over at the PC and its running smooth.

I also saw in the manual for the PJ that another optional hookup is an RGB plug from the PC to the HDMI to the PJ. Would that possibly be the problem?

How can I, if I want to project what's on the laptop on through the PJ to the screen? I need to run both.
