Get a cheap TV tuner card with composite input. (any of them have this, i suggest hauppauge wintv go, i used to use it for my N64)
then get a converter from radioshack to convert the yellow/white plugs to a stereo plug and input it into your soundcards line-in. works good.
otherwise the best way is if you use a LCD that has dual inputs like the dell 20 and 24inch models, you get s-video input or component input.. still have to do audio the way i said tho for my first example.
the LCD way, you can play in PIP mode over a fullscreen game. and it also affects performance 0%.
with the tuner, you can do it in a window or fullscreen, but cant overlay a fullscreen program. also it affects performance of course.
i did the tv tuner example in my early college years about 4 years ago. getting yourself a 20inch 2005fpw lcd will be a big favor to yourself though, it has s-video input and composite.. a lcd is nice anyway.
if you are against that, get a $30 hauppauge win-tv go.
ps. i used a ati tv wonder back in the day, just do yoruself a favor and get the hauppauge.
if you dont believe me i can lead you to my posts on rage3d trying to figure out all their software issues (which they eventually just DROPPED support)
get a hauppage. :thumbsup:
