Component Video Switch PROBLEMS - Help!

I have a problem with my new component switch. Whenever its on a HD channel (primarily 720p, like ESPN HDTV), it will come on, then after about 10 seconds go off for about 5 seconds, then come back on. A little static appears before the picture goes bye bye.

For the record, I have a Toshiba MT-80 projector, DirecTv satellite and high quality monster cables all around. I tried switching cables and still had the same problem.

The component switch I am using is the Dynex, which I bought for like $45 from Best Buy. My PJ is 720p and 1080i compatible, along with the DTV source. The Dynex says it is compatible with both 720p and 1080i. But I have played around with all the settings and can't figure this out.

When the picture is on the screen its beautiful. But it appears the switch can't take the bandwidth or something...not sure what this means.

If I need to post a video, let me know.

Thanks for the help!

Thanks for the responses...

I have had no problems hooking the PJ up to the D T V box directly.

I don't think its the power supply. I have all of my equipment plugged into a Monster Cable Power Center. More than sufficient. There is also proper grounding.

I can view other channels no problem. Or, when I am watching sportscenter in HDTV, when the non-HD commercials come on its fine. So it makes me think its the resolution thats causing the problem.

also, I tried pressing the resolution button on the D T V box, but it won't change. Is there a way to force 1080i?

plus, if the component switch is 720p compatible, I don't see why this should be happening...

Thanks for the insight!
