something wonky about using files from a DVD?

[Mr Downtown]

A client sent me a DVD of ordinary TIFF and JPEG photos and logos, rather than the usual CD. My G5 Dual seems to mount it, but when I try to import the photos to InDesign or open them in Photoshop, weird things sometimes happen, as if the file is lost. Even the Finder seems to do odd things. At one point files would disappear from the listing as I clicked on them, at another time I had to quit and relaunch the Finder. Are DVD files just naturally wonky?

I've had that happen before.
Try to copy the files you need to your desktop then eject that nasty thing!
