I made a CD of B&W photos that I posted on Flickr. I made a DVD of color photos from my Flickr. I popped the CD into the DVD player and was able to see my photos. Some looked good, others too contrasty and or grainy. I popped in the DVD and got nothing but a "cant play disc" message. Anyone have any ideas what happened? Oh,I did view them on computer and they both worked just fine. Thanks , Joe
