Hi, I'm a recent mini owner. I have a powerPC mini I picked up a few months ago. I'm trying to get TV out to work. I have a _really_ old TV, no fancy HD tv with fancy plugs for me. (The brand is "orion," I believe.)

I have the apple branded DVI->RCA/S video converter connected to the mac. I run an rca cable from that to my receiver to the TV.

The mac recognizes that a TV is attached, I get a picture, and I can change the resolution and muck with the various settings (I get different resolution options than when I have my LCD plugged in directly, so that tells me something's working).

The problem I'm having is with picture quality. There are like (I'm not sure what to call them) two scan lines that slowly traverse the screen from bottom to top. Sllooowly. It takes like 5-6 seconds for each to complete the cycle. Hard to ignore them, say, if I want to watch a movie.

Has anyone had this problem? I realize my description is kind of vague, but any pointers would be appreciated. I've been searching online all week and read other issues people are having on this forum, and know that it's possible to get a good picture out of the mini... Hope it's not my TV -- I've actually gotten a fine picture on it by using a PC with a TV out graphics card. Thanks!

It almost sounds like the DVI to video adapter isn't seated properly or you are experiencing cable interference. You may want to try reseating the adapter and trying out another RCA cable. You should also try lowering the refresh rate in System Preferences > Displays if you are given the option.

Yeah, I think that made a difference. (I changed RCA cables and plugged it directly into the TV, not through the receiver.) Thanks!

I glad to hear it turned out to be an easy fix.
