I'm not trying to be an ass or something but I had to reread the post several times to get the subject (which I still dont). I know that it could be the fact that English is not the OP's primary language. There is always improvement for everybody.

@cmoney333: which connection gives you the lines rolling? HDMI or comp?

The rolling lines are caused by interference leaking into your component cables, which are analog lines. Long cables (i.e., 50ft) are more susceptible than short ones. The most common source of interference is AC power. The easiest solution is to make sure that the component cables are as far from any AC power cords as possible. A better solution is to invest in high quality component cables that are shielded, which minimizes the amount of interference that can leak into the cable. The HDMI cables are far less susceptible to low frequency (AC power) interference because they carry a digital signal.

Anyone can see the future, ...if they wait long enough.

If your "rolling lines" look like this:




then the problem is ground loop.

My friend had a similar problem and he identified his cable connection as the source. He solved the problem with a ground loop isolator connected b/w the cable coax and his cable box:

I also had the rolling lines of ground loop traceable to my cable connection. It was apparent when I used the component connection on my Panny PTAE900u projector. The cables were custom made 25 feet long Quad-shielded RG6 Beldens with Canare connectors (bluejeanscable.com). The HDMI connection didn't have this problem. I thought the quad shielding would protect against any AC line interference but after some testing I identified the cable connection as the source of the problem.

Here's another example:

I used this CENCOM isolator which doubles as a spike protector and it eliminated the rolling lines and ground loop.
