Hi, I've not posted on this forum before, but have enjoyed reading it as time permits. I work full time as a photographer.

I don't have Lightroom 3 yet, but from your screenshot it appears that if you burn directly to disc from inside Lightroom, the exported files must sit in a temporary folder until the disc is burned and then they are deleted. In the 64-bit version of Lightroom 2 (which I use) you can't burn to disc inside Lightroom at all. So if you want to hang onto the exported files AND burn a disc, just export the photos to your hard drive and then burn those to a disc after the fact. This way you are able to save the exported files to review if needed. I like to save them as well.

Hope I've been of help.
