Adrian, I'm running a HTPC at 720x480 using component video out (best my analog TV supports). The resolution is extremely low for desktop use, but works just fine with Media Center and Game EX. You should be fine running your ROMs since most don't support higher resolutions. The only issue that you might encounter is if you want to run Amiga games or the like which require a higher resolution. S-Video can only provide low resoultion support and the quality is okay. You will have to make a judgement call on the ROM game quality assuming thats your main concern. As you step up, you will probably want to go with a EDTV or HDTV that will support higher resolutions. These digital TVs support digital connectors. When you reach that point, you will want to get a new video card with a DVI connection (unless your onboard video has this already). DVI (or HDMI with an adapter) supports true digital high resolution and the quality will be as sharp and crisp as a high quality monitor. The quality of your connection will matter so go in the following order from analog to digital. Analog (from lowest quality to highest): Composite, S-Video, Component Digital (higher resolution support): VGA, DVI (HDMI). Hope that helps.
