i have my computer hooked up to my crt widescreen tv... works well.... pictures on the tv look very similar to when i watch a normal dvd on the tv. my video card has a svhs output that i connect to the tv's svhs.... i use NVIDIA nview desktop manager and i can either right click on a video and select 'play on my tv' or drag the wimdows media player screen with the video playing off the right hand side of my monitor and that appears on my tv....
