yes all the ends of the cables I have are the 3 striped kinds. That's why I wanted to know if the stock cable that comes with the original device has something special about it.
Either way I have been reading up on RS07 TV-out related thread and did see your screenshot with the weird scanlines. I also watched those YouTube videos from Johnny Liu who has done extensive testing and mods to these devices. He has the same problem you do and says CFW 1.3.2 was the last one that worked for him. CFW 1.33.4 didn't work for him and also had funny scanlines at the top portion of the screen.
I know the dev team is looking into it, so I guess I'll also wait and see if a new CFW revision will help solve the problem. If it does for everyone else except me, then I can rule out that the FW works, and maybe its my cables that don't. That case would be more definitive to me.
Unfortunately right now there are several variables I cannot rule out which exactly is causing my problem. But I do think my greenish screen with the fuzzy marks is not an effect anyone else has encountered or described yet, so it could be a cable issue since I assume everyone else has the right cable, and mine are not original lol!
