What Nero Do I use As I Have Problems?

I got my new computer at Christmas and its a Compaq (HP), and I run Windows XP. I can download a vidio (avi) and then convert to VCD using WinAVI 7.7 like I have always done. When I look at the avi or vcd format of video on Windows Media Player 11 it looks beautiful. Then after converting to VCD I burn vcd format on Nero Burning Rom 6 ( and it looks darkest and nothing like the beautiful showing it showed on Windows Media Player?? I have “K-Lite Full Codec” installed. Could it be my burner causing the bad copies? Please, any and all help is deeply appreciated.

PS - Should I try Nero 7?
