I have a Duo-R, but for the moment I'm stuck with a 3rd party set of composite AV cables. I'm running my TV in game mode and that fixes any latentcy issues, but I have other issues, such as the picture dropping out if the AV cables are nudged even slightly, a painful sort of buzzing noise in places where the game is silent, and occasional sprite flickering that had monsters occasionally turning invisible for a few seconds when I'd enter certain areas in Ys I+II. Is this primarily an issue with the AV cables, or is it just the nature of hooking up these older consoles to modern TVs? Up until now, I had only ever hooked up older consoles to tube TVs.
Forgive me if I sound like an idiot here. I'm just not terribly familiar with a lot of the technical details in how HDTVs interpret these things. Eventually, it won't be a problem, because I intend to have my DUO modded for S-video. However, I'm not in a place where I can afford that, so any tips to reduce the issues I'm experiencing right now would be highly appreciated.
