CD DVD Driver

Hi there, This is my very first time here, and I’m glad to have found this site stuffed full of interesting topics.

I have a question about the free download CD DVD driver recommended on site. Would downloading this driver cause serious problems to my existing driver on my PC with windows vista home instaled and includes Blu-Ray & HD driver with Realtek Audio instaled?

My reason for asking is that I would like to split downloaded audio programmes which are slightly bigger than the audio cd can manage.

I hope you can advise me on the best way to go on this
