I have a box of Bulkpaq orange and find that they are ok for <4Gb burns but >4Gb and they tend to have major read errors. <4Gb the error rates are high but don't prevent reading.
Personally I find Verbatim Printable DVD-R, Maxell DVD+R, Ricoh DVD+RW, and Maxell DVD-R to be very good on this drive. But cheap media is a hit or miss afair, for example good Princos and good Ritek G04s burn beautifully but bad ones are coaster material.
My summary, not a drive to risk cheap media unless you don't mind risking low quality backups.
As for data backups, the DVD-RAM may be a slow format but combined with a compressing backup tool (I use the Nero one) it is fantastically reliable.
