Cannot view vertical .jpg's on new Toshiba dvd player

[dsf]

When I look at a slideshow of my digital pictures on this new Toshiba SD3950SU dvd player only the horizontal pictures show up on the screen! The vertical ones do not show, and there's an exclamation mark inside of a small triangle in the upper right corner where they should be. I shoot (for a living) with a Nikon D-1 and make .jpg files in the camera, and rotate and Save As in Photoshop 7. Images are burned to a cd on my G4 Dual 1g. Again, the horizontal frames show up beautifully, but the rotated verticals do not. The manual says to rotate the images in Thumbnail view and they'll play fine, but they don't show up. Toshiba's 'help' site is useless. Can anyone help?
Thanx,
Don

rotate the images in Thumbnail view

???????? why

Do not have/use your software but have over 3000 jpg family photos, from at least 5 different camers, various resolutions, angles, croped, trimmed, text added, rotated. Generally I just burn everything as a data disk and most players have no problems. I put an pc exe vierer program and autorun in the root dir of disc so it will play on pc's without the need for installed program

Snafu,
Thanx. I just copied the files to the cd and burned away - no slideshow program was put on the disc because the Photo Viewer component of the dvd player is supposed to make the slideshow work... which it does for the horizontals. So, whazzup with the verticals?
Thanx,
Don
