[MacDV] Re: iDVD encoding

[R B Williams]

iDVD definately creates a huge temp file folder on the boot disc. My evidence comes from a power failure during encoding. After restart, there were more than 600 invisibles on the boot volume that were logged by my disc utility during the repair process, all created in the last
hour prior to the power failure.

No harm came to the project, I just started over with the encoding and all went well.
