I'm not sure, but I doubt that Nero 5 will support your burner.
Many people are still using Nero 6.6 because Nero 7 has introduced a lot of bugs that are only slowly being fixed it seems. I'm using Nero 188.8.131.52.
You could also try some free general purpose burning programs if you need to burn data instead of video.
Here are some links to free burning software:
ImgBurn (burns "images" of CDs and DVDs but cannot be used to burn files).
AVS Disc Creator Free (I haven't really tried this one).
CDBurner XP Pro (It's a bit unstable in my experience).
DeepBurner Free (I haven't really tried this one).
