OT: Burned JPGs sometimes not displayed on DVD player

I raised this some time ago in the alt.comp.periphs.cdr NG, but
although I had some helpful suggestions I'm afraid the mystery
remained unsolved.

Using Nero on my XP-based PC I burn some folders of JPG photos to a
CD. On playing this CD on my Phillips DVD player, a minority of the
JPGs do not display. They can be opened OK in any image editor, and so
far I've found nothing whatsoever that distinguishes them from those
that do get displayed. I'm completely baffled. Anyone have any ideas
on the likely cause please?

Thanks, but no, all JPGs the same - none ever saved with the
progressive option.

Then the second most likely is filenames containing characters that are
not compatible with ISO9660 Level 1.

ISO, joliet, can't keep trak of it all but I bet yer right. I was
told in the mp3.hardware group that directory name length, depth,
and filename length vary from player to player.

What's a progressive jpg? Sounds like politics ;)

One problem replaced with another ;-(

After much experiment I finally found that I could get 100% reliable
displaying of all JPGs by resaving them at a fixed 'quality' setting.
(Scale depends on software, of course. I used '80%' in ThumbsPlus,
i.e. towards the high quality end. This was arbitrary; for all I know,
*any* quality would work, but no time yet to try - nor enough spare
CDs!)

But, after displaying all photos in the first 11 of 20 folders, the
DVD finished playing. I could then see that it was only *showing* 11
folders in its menu. Yet all 20 can be displayed on the PC.

I burned another with identical settings, just in case. Exactly the
same occurred.

Any suggestions please?

Just to avoid confusion, you did say CD originally.

Fair point. The DVD PLAYER finished playing the CD-R!

See if you can find out your track and sector size. I can't shake this
feeling that it has something to do with files starting at sector 0
on each track. I have no idea how you'd accomplish this, other than
to write some kind of padding file.

Both CD and DVD use ISO-9660 file systems.
There are no tracks (a CD/DVD has one spiral track) and a block size of
2048 bytes.

Any thoughts on the remaining mystery of non-displayed files please?

Where did PhotoShop come into the discussion?

Files = JPG, source = identical, all described earlier.

Do those files have image information such as EXIF or IPTC?

Yes, all of them.

Files always start at the beginning of a sector. The filesystem
contains pointers to sector numbers, not to individual byte offsets.

I know this - and I have found a way to make Windows 98/ME safe against
this bug. Involves using MSCONFIG.

OK, what does F0 0F C7 C8 do?

The good news is that nothing is compulsory.
The bad news is that everything is prohibited.

There's also RPI for Reconfigure Programmer Immediate.
