CD's coming out dark?

Hi, I have Windows XP and I have a video that plays in Windows Media Player as it is in avi format. I

convert it to vcd format using WinAVI converter and then burn it to a CD. I go to plat the CD on my DVD

Player which is connected to my tv and the CD play comes out kinda darkest. But on the computer using

Windows Media Player its perfect. What am I doing wrong. I use Nero and K-Lite Full codec. Would

upgrading to Nero 7 help?
Any and all help is deeply appreciated. Many thanks. :frowning:
