Errors burning cdi images

[terminator]

there´s no need to change the default values.

a possibility for buffer underruns is extensive
surfing/filesharing or you just opened outlook
express while burning an made a coaster .

try to simulate the burn.
check the dma settings of your drives.
try to connect harddisk and burner on
different ide-channels.

if this wont help you, i´m sorry, i have no more ideas.
