Nero 6 error logs

Can anyone tell me why my burns on two different brands of discs failed. I finally managed to get some video to the HD from a home movie dvd. The “burn process failed” when I attempted to get this small clip all by itself on to a dvd.

Windows XP, Nero 6.6.1.15, ATI Radeon 200 Pentium® D cpu 2.80Ghz
System memory 445mb cpu 2800 mhz bus 200mhz
dvd burner drive: TSST Corp SHS182D

Thanks
