Check whether the software you're using supports your CD-R. If not, try downloading an upgrade, which possible supports your CD-R. If you can't find an upgrade that does this, try a different software.
If the problem persists, I'd recommend a firmware upgrade for your Teac.
I don't think that the problem is caused by the blank CD-Rs. Almost every brand supports speeds higher than 4x.
Is everything on the Device Manager fine? What about the Bus-Mastering drivers?
