The only DVD burners I would suggest are the:

Lite-On LDW-411S
Lite-On LDW-811S
Nec 1300-A

These are top of the line DUAL DVD burners and aren't really expensive.

I mean, 8x burner&#39;s transfer at about 10Meg&#39;s per second..... can a 5400 rpm disk keep up with that? </td></tr></table><div class='postcolor'>

All dvd burners use technology similar to SMART-BURN to avoid Buffer Under Run errors.
