Burned several DVD-R and DVD+R discs all with good quality CBR MP3s and i've also obviously read the manual and tried numerous different settings and even a few different authoring softwares. MEP 7000 refuses to read any of the DVD discs, i wonder if the problem is perhaps that i need to use a particular disc from a specific manufacturer, can anyone here help?

Haven't heard of any issues. I used Max or Sony I think and they were read fine.

What SW programs to burn with are you using?

CD-DA, Nero & CD Burner.
Will buy and try Max DVD-Rs next.
I already use Max CDRs and they are ok.

Thanks for your reply.

It's obvious, but you checked to make sure the discs are closed right.

Yeah, that would be my first suggestion - ensure that you've finalized them.
