I assume, that DVD43 (non free) indeed left something "behind". Make a note, where it has been installed, then uninstall it. Delete it from your "Program Files" folder, if there are some "left overs".
Then check, if it loads a driver. Use regedit, goto
Look what is in LowerFilters and UpperFilters. If you are skeptical, delete everything. If some app stopps to work, you can reinstall it.
AnyDVD only uses "AnyDVD" in lower filters, "ElbyCDFL" is from CloneCD, "ElbyDelay" from CloneDVD.
