If it isn't, check the manufacturer's web site, or Google for a review of the unit.
Since you didn't supply the brand and model, it's not possible to provide a better answer.
I bought a VCR/DVD unit and there is no mention in the booklet about the proper DVD-R or DVD+R (this unit handles both types) speeds to buy. This unit came with 5 DVD+R's 4.7 gig.
I was at a store today and saw these discs with 8X and 16X speeds. Which should I buy for my unit? Will my unit be able to handle both and how about when the speeds increase? Thanks.
