disc juggler with buffer error

[amokk8]

so i have like 8 zip games in the .cdi format that i want to burn. but everytime that i try to it will burn fine with no problems until the last second when the buffer starts to slow down.

so it'll burn at 99% and the buffer reader goes from 98% to 1% and then it'll say "error: buffer under run or read error"

is there something wrong with the file or just my burner? i have no idea so any help would be appreciated.
