Need help with my dru-710a :(

i just got this dvd burner about a week ago and i have a question. do i have to have the analog or digital audio connector on the back of this drive connected to get the best quality burns or does it not matter?

It does not matter.

Use latest firmware to get best burns. http://codeguys.rpc1.org/firmwares.html#DRU-710A
