rundll32 problems

I recently installed software called “AVS Video Converter� and now whenever I
try to burn a DVD using Nero I get an error something like “Windows host
process rundll32 has stopped working. The program has halted.� Recently the
problem has gotten worse and I get multiple error messages in rapid-fire and
I can’t close them down fast enough so I need to reboot to get my computer
back.

The fact that I recently installed the aforementioned software may or may
not have anything to do with it. I know that the first reaction is to
uninstall the AVS software, and I may do that. And maybe need to reinstall
Nero. But I’d rather fix the problem if possible.

I’ve done a little research on rundll32 and learned that it is a file that
allows similar programs to use the same resources. I also read that
sometimes a registry tune-up can fix problems with rundll32.

I’ve gotten some good help from these newsgroups so I decided to get some
advice here before proceeding.
