Okay... after some experimenting, I've concluded that Burn-Proof doesn't work correctly from CDA5. If I enable it, the buffer empties every 30 seconds... and writing stops and restarts each time. If I disable it... with the very same project... the buffer stays at 99% during the entire write process and the burn goes perfectly. This is with a Plextor 24x10x40 drive.
