JPEG limitations

Anyone know the limits of JPEG files on the LiteOn range (specicically the A760) ?

I have disks with images that do not display correctly. Thumbnails are ok but sometimes no full image or it is distorted.
The images are high res (over 3000x2000 pixels) and all over 3MBytes.
They play ok on a Philips DVD player and Hitachi DVDR.

According to a review of the 5055gdl+ the highest resolution they checked was 2272x1704 and that worked OK.
