What kind of DVD media are you using? DVD-R or DVD +R?
Read the info in this link where he talks about burning DVDs from external burners. Sounds like there are problems burning DVD-Rs in external drives using USB, and that the solution is to either use DVD+R media or an external drive that uses firewire.
