When I transfer my jpeg camera images directly to CD/DVD, my DVD player has no problem displaying them. However if I process them via Adobe Photoshop CS3, and save them as jpeg images, and transfer to CD/DVD, the machine refuses to recognise them.
"I've put the originals and the PShop images on the same disc - the originals play, but the Pshop don't."
If you burn files to a CD, then close the session, it's possible to return to the same CD later and burn more files on any remaining free space. But - in my experience - if you do that, the first session is no longer accessible.
Could this be the explanation? Have you tried burning your Photoshop jpegs on to a disk by themselves?
Have finally solved problem by using Photoshop Elements v. 2.0 to convert the Photoshop CS3 produced jpegs to Ps Elements jpegs - which now play fine. There must be something about the CS3 jpegs which are different. God knows what, because they were all saved as standard. Anyhow - thanks everyone for your contributions. Would still be interested in explanation if anyone finds it.
