I think we need some long name support as Rockridge would. UDF would not really be needed from a data point of view. I found that a windows free software runs under wine that will be a workaround if any one wants to make true video player UDF video with in puppy. - Wink

Slacko 5.5 has cdrtools 3.01a08. That should be a good testbed.

Do we need the Rockridge ????

In my tests using "iso-level 4", I still need Rock Ridge to provide upper/lower case filenames, in Linux.

[Edit] Somehow, XP was able to see the full upper/lower case filenames.
My intention is to keep Rockridge always for level 4 and never for level 1. Like that, there is no option for the user.

Yes, imgburn is a good one. It was one of my favorites when I was still addicted to Windows Smile

rcrsn51 is right. Rockridge is required not only for long filenames but also for other Unix stuff like permissions, more fine-grained timestamps, symlinks, etc.
My recommendation is to *always* enable rockridge (RR) no matter what iso-level you use. It does no harm for compatibility (those who don't understand RR simply ignore it or pretend that it doesn't exist), and the additional space taken is infinitesimal. Anyway, what feature do you plan to offer that makes use of "iso-level 1"?

Got it - thank you

I think pBUrn can use isolevel 4 by default, but isolevel 1 is most compatible with whatever os out there, I see it logical to give an extra option.

"Use 8.3 naming of files for backward compatibility"
- Ok, that sentence is awful, but still my intention Smile

edit: what about
"Use old file-naming (8.3) to work on older systems."

Agreed.

"Use old file-naming (8.3) to work on older systems."

How about:
"Rename files to comply with DOS 8.3 filename convention"? Googling for "DOS 8.3 filename convention" brings you straight to the Wikipedia article about it (or, if you can do it from gtkdialog, you may want to provide a URL link directly to that wikipedia page).

Alternatively:
"Most basic ISO 9660 specification (limited features but most compatible with all operating systems)"

cheers!

I went into town to download the new Fatdog64v621 at a family member with high-speed cable internet. Had a good simple supper with them, and when I got back, saw flashes of distant lightening. Like a magnet drawn to metal a megacell cloud started six counties over is heading my direction. Now a under a Severe Thunder Storm Warning and one eye is on the TV radar, and other on the burn time remaining....

... As I see it right now:
- Replace isolevel 3 with isolevel 4, and remove the Joilet options. Do we need the Rockridge ???? Remove udf as well.
- Keep isolevel 1 for backward compatibility
- Depend on cdrtools ONLY
- burning video, filesystem settings are not available for user, so not any issue with udf here...

This would make it all easier for the user (Less options).


Any opinions?
Sigmund
Seems reasonable. And, as pointed out by @Rcrsn51 RR also maps.

Fwiw:

Options aren't hard if it is obvious what they are for (and perhaps any downsides) e.g. if an option has a label or tooltip saying "long filename support on win95/98" or something. And an option for downward compatibility with Win98 isn't such a bad idea when some of your users are still using machines from that era. Just the other day someone was asking here for help installing NT3 or something... Wink

May be the storm affected the burn resulting in unworkable bluray ... Confused

That being said, multisession save is now logged in /dev/initrd.err (this file is not persisted across reboots). If you want to see what's the result coming from the "final" multisession save at shutdown, instead of doing a real shutdown, type kill -3 1 instead. That will tell init to shutdown everything like real, but instead of powering off it will give you a console at the end, and you can inspect the result of the final save in /dev/initrd.err. From here, type /sbin/poweroff -f to poweroff, or /sbin/reboot -f to reboot. If you want to stay around in that console for longer, /bin/mount -t proc proc /proc might make it more comfortable otherwise you will have to prefix everything with the full path (e.g. /bin/ls etc).

I thought this might interest some. Apps-on-Blu-Ray

Interesting use for external Blu-Ray devices. Free tools for PC users, too.

I have a eye on external blu-ray for my new 64bit Netbook, but I think I'll make a remote save session first. seems easy enough. Almost the entire work is already in Fatdog64 multisession code. Came across how to feed a cdrecord burn stream to a remote burner. Network is faster than burn rate so it would work. Wink

Yes I made it under the wire on the burns weeks ago. I Added md5sum check code to my burn/build scripts, was checking them just after a burn, but last night the weather people said storms tonight so I been skipping the 20min check to get done backing up a 500GB hybrid drive for reuse by now. Second to last one (18 discs) just completed. The final one is not maxed out so I'm looking for stuff to fill it.
