Buffer Drops to 7% While Burning.

I am having some problems while burning with Nero 6.6.

My recorder buffer level keeps droping to 7% at random intervals throughout ther burn. My read buffer is ok just the device buffer drops.

Does anyone know how i can fid out what is causing it. The only recent change that i can think i have made to my system is that i have switched from MSAS on active to Counterspy on active. There might be other changes ive made but cant remeber.

How do i find whats causing this and how do i fix i

thanks

 

Are you using the same media that you always have?

Also, what make and model burner do you have?

What XP version are you using, and have you been updating it?
