Indeed, that's correct.
And, Pioneer tech support is either lying or clueless because they say the latest firmware should work.
seems, they don't know their own products;)
Seriously, the D series Pioneer DVD burners are not specified to write DVD-RAM. Just read the spec sheet from the link posted by Whappo.
In short: if you need DVD-RAM writing, the 216D is of no use for you (unless you are using other media also)
Their media list is a joke. It states write speeds for DVD-RAM :rolleyes:
And the specs document from the same location does not list DVD-RAM in the write support section.
