Depending on whether you are looking at DVD+R or DVD-R, the ComUSE Memorex can be any one of 2 to 4 different media types. The packaging is no predictor, except that the gray base is always Ricoh. Black base can be Ricoh, CMC, Prodisc, MCC, you name it.
Personally, I think there are much better deals around for $1 per disc, and you'll know what you're getting. Maxell at Office Depot right now is one of those deals.
