Again my suggestion stays the same, use the command I posted:
Code:
growisofs -dvd-compat -speed=1 -use-the-force-luke=bufsize:32m -Z /dev/dvdrw -graft-points -rational-rock -full-iso9660-filenames -iso-level 2 directory/to/burn
It has options that prevent strange things from happening, like the things that you are experiencing.

To preserve permissions you should indeed use tar. But why not make several tar archives each less than 2 GB. That would work best.

Ok.

To preserve permissions i can make several tar archives with less than 2GB, but can i burn them(tar files) on to DVD using growisofs?? And also i doubt that there will be a wastage of remaining space on the DVD if i create a file with less than 2GB and burn it on to DVD.

Ok, so, make several tar archives each of less than 2 GB, but adding up to a total of around 4 GB (less than 4480 MB), then burn them all to the DVD. The DVD can hold around 4480 MB or so, so you make many archives, put them all in a directory and burn the directory (just put in the path to the directory containing all the tar archives).

They're probably front ends to cdrecord/wodim or growisofs.

There are a few caveats.

The DVD disc holds 4.7GB of data (assuming not dual layer). But the filesystem has that 4.3GB file size limit. To be safest, keep the individual files below 2.1GB and all is good. Keeping the files smaller also helps if / when your optical media goes bad. You'll still be able to recover SOME of the data on the smaller files not affected by age / scratch / and other degredations.

Burn using a directory, or create an iso image of that directory and burn it. I prefer the iso image way. The actual burn goes much quicker IMO. But you're left with basically two copies of those contents which you might not have room for in the first place. But in the case of a video dvd where you might make multiple copies, speed is king.

Another quirk is that your burner might not even work in linux (not to imply that it'll work in windows either). For some drives you do not have the option to use the -speed option. Letting it default to it's speed ups the odds for a successful burn. Factor in that burners burn out, so don't expect it to last as long as a harddrive if you use it as much as you do a harddrive. If you live in a dusty place or someone in the household smokes, you might even need to clean the lens on occassion. Qtip plus rubbing alcohol works for me. Let it fully evaporate away before trying to use it again. Not all drives give you easy access to this lens, if at all. And other mechanical issues.

Your actual discs should be kept in a dark place. If they weren't well shielded from light, especially sunlight while it sat on the store shelf for six or more months. Then you might not have any discs good enough to be successfully burned. And don't expect the discs to be a long term or reliable backup medium.

As far as the options. -J (joliet / long file names) -R (rock ridge / permissions). You want these options and they are not defaults. The iso9660 filesystem defaults to 8.3 DOS like filenames without these options. While you don't technically need these options. They'll make your *nix life easier.

So...

$ growisofs -Z /dev/dvd -J -R ./PATH/

Or...

$ mkisofs -J -R -o image.iso ./PATH/
$ growisofs -dvd-compat -Z /dev/dvd=image.iso

If unsure use a GUI front end like k3b, or brasero, or nero, or....... They package these up into clickable selectables, instead of referencing a man page or other I can't quite remember measures. Also make sure that your user has permissions setup to use the device. i.e. in the cdrom group, or burner group, or however your distro has it setup. Otherwise you might only be able to burn as root, at which point you may seriously consider NOT using a GUI app for the task.
