I may be missing something but I don't believe the status of encoding showing DONE would cause the buffer underrun error. As far as I know the process goes is that using background encoding simply helps speed up the final stage of burning a disc. If you don't have background encoding on (like me - it caused all sorts of performance probs) when you hit the burn button it will do all the encoding and transporting and escalating and myxomatosusing before creating a final disc image. It is not until the completed image is created that the burning to disc takes place, correct? Disk fragmentation or other processor intensive tasks while burning would be the first places I'd look. Cheers, Coj AnonBilly <anonbilly at dockpoint.net> I am using Best Performance. (With Best Quality, Background encoding is greyed out) And I am using the background encoding. The Status Tab did show DONE for all Assets. Thanks for the support!
