Adaptec ASPI was a guess - but I wouldn't be surprised if you find it is on your system. Is there an aspi32.sys anywhere in your Windows folder?
If you try my Adaptec ASPI removal instructions and find you haven't got an aspi32 entry in "Non-Plug and Play Drivers", then you hadn't got Adaptec ASPI installed after all.
Roxio burning software hasn't used Adaptec ASPI on Windows 2000 or XP for some years.
Nero 22.214.171.124 is pretty recent - it came out around the beginning of March 2004. Nero 126.96.36.199 is indeed older - in the Nero 6 series, Nero 188.8.131.52 was current at the beginning of March, and was superseded by 184.108.40.206 in mid March.
I'm not going to guarantee that 220.127.116.11 has full support for the Pioneer DVR-107D. I know this version adds full support for the NEC ND-2500A, which earlier versions of Nero 5.5 lacked.
Personally, I only have a retail serial number for Nero 6, so I'm less clued up on Nero 5.5 than on Nero 6.
