I upgraded my 5.5 to version 6. Works well and comes with a lot of toys. It should recognize both your drives. They have a rather good database of burner types.
The downside is that you can't coexist with 5.5 until you determine if you like it.
You get a free evaluation for a short period. It's also kinda cheap and not Roxio or whatever those doofs are calling themselves these days.
I have a DVD reader and a CWRW on my box and have no problems at all.
