What speed are you burning at?

Have you tried to burn slower?

Are you using quality media?

Is the drive USB 2.0 or USB 2.0 Fast?

Typically USB devices are either 2.0 or 2.0 Fast. The fast version has speeds as fast as firewire, while the 2.0 has speed as fast as a snail. I would hope that the drive is 2.0 Fast, but if you're on an eMac, I dunno if they had 2.0 Fast ports. Anyone know if they did or not?

Have you tried different media in the drive? Perhaps try an Apple or Verbatim disk and see if it works with it.

Are the files on your Internal HD or are they on an external?

Emacs only have USB 1.1 ports, which move data at 120mbps.
We have six at work, four are Emac 700, one is an Emac 800,
and the last one, we got three weeks ago, is an Emac 1GHZ.
All are USB 1.1 ports.

To fix your problem, you'd be better off returning the external case,
and getting a USB/FW combo external case, that way you can burn via FW, and knockout your BU problems.
I do what you do ( Source DVD in the emac DVDRom drive, Blank in
the FW attached external burner) and only FW spools the data
fast enough to avoid the BUruns. Try to match the read speed
and the burn speed minus one to help further, ie. if your
DVDROm reads at 24x and your burner burns at 4x, a 2x burn
will help mimize BU runs.

Of course, nothing beats burning data direct from HD 2 DVD-R.....

USB1.1 was renamed to USB 2.0

How much memory you got?!
Bufferunderruns can come from not enough memory!

also from the data being chocked up as it goes from computer to external recorder!

Do what Terryj says. Your USB ports are too slow for burning DVD regardless of what the drive or case say is possible. You must connect your drive via firewire.

What a bunch of Weasels!! When the heck did they do that??

I know there's no point in asking Why they did it.
