What media to use with old Apex DRX-9000?

Anyone here still have an Apex DRX-9000 DVD recorder? I was given one and it works… but only with older media. Does anyone still have one and if so, what modern media (16X) does it work with?

It just failed on a Fujifilm 8X media today. I know it works with old Memorex 4X DVD-RW but can’t find that anymore.
