OT: some JPGs do not display on DVD player

[Terry Pinnell]

Using Nero on my XP-based PC, yesterday I burned a lot of JPG photos
to a CD. On playing this on my Phillips DVD player, a small number of
the JPG 'tracks' did not display. They can be opened OK in any image
editor, and so far I've found nothing distinctive about them. Any
ideas anyone on the likely cause please?

Terry,

Look at your Philips manual very carefully. You may have picked the wrong
JPG option when you clicked "save", or it may not like very high res
pictures. I have a JVC DVD player, and it is rather particular as to JPG
file type.

For NTSC, anything other than 640 x 480 will take longer to load. For PAL,
that may be different. Note, the 480 comes from the fact that it is the
number of NTSC visible horizontal lines; i.e. the vertical resolution. The
640 (480 x 4/3 ) is about the maximum horizontal resolution that a very good
non HD set can resolve, when fed through a video (not antenna) input.

Thanks, Tam - I hadn't appreciated that DVD players were fussy!

Hi Terry,

There are a number of reasons that I can think of off the top of my head

1. The file extension may not be what your DVD player expected. For example
your DVD player might expect all pictures to have the extension .JPG

As you can understand the extension .JPEG is different though your windoze
computer won't see it that way and will display the image as you expect.

2. Your DVD player might not support long file names, or file names with
multi-byte characters.

3. The JPG could be saved as progressive instead of "Normal". Use a program
called IrfanView to determine if the files are progressive. Select the file
then click Image, Information. In V3.85 it tells you if the file is
progressive in the "Compression" information.

Hope this helps,
James

Hi Terry,

Thanks, James, but I'm afraid none of those apply.

1. The file extension may not be what your DVD player expected. For example
your DVD player might expect all pictures to have the extension .JPG

As you can understand the extension .JPEG is different though your windoze
computer won't see it that way and will display the image as you expect.

All are JPG.

2. Your DVD player might not support long file names, or file names with
multi-byte characters.

Longest file name is 27 chars and it happens to be one that does
display.

3. The JPG could be saved as progressive instead of "Normal". Use a program
called IrfanView to determine if the files are progressive. Select the file
then click Image, Information. In V3.85 it tells you if the file is
progressive in the "Compression" information.

All are saved as Standard.

Hope this helps,
James
