Why will burned video dvd's not mount and why are those dvd's wrongly seen as empty in 13.04?

Why will burned video dvd's not mount and why are those dvd's wrongly seen
as empty in 13.04?

This happens with all selfmode DVD's I have. Created those quite some time
ago on Windows XP with Nero. My DVD player autostarts the DVD's. Windows 7
also plays/sees the files on the dvd's Commercial dvd's open normally,
just as selfmade data dvd's (old ones made with Gnomebaker), as do audio
cd's and data cd's. Later created these simple dvds on Vista with Nero and
later with Nero for Linux; probably ubuntu 10 (I think). A few (illegal
movies) and most dvd's are music bootlegs. The dvds are named and have two
folders that's all: [empty] AUDIO_TS and [containing files in] VIDEO_TS.
Might this be an UDF issue? And should as I saw somewhere /etc/fstab be
edited to include UDF specifically? Installed and reinstalled: libudf0,
libudf-dev and udftools among other things. Manually mounting gives the
following: sudo mount -t udf /dev/sr0 /media/joost
output: mount: blok-apparaat /dev/sr0 is schrijfbeveiligd en wordt als
alleen-lezen aangekoppeld mount: onjuiste bestandssysteemsoort, ongeldige
optie, ontbrekende codepagina, ontbrekend hulpprogramma, slecht superblok
op /dev/sr0, of een andere fout Soms staat er nuttige informatie in het
systeemlog -- probeer zoiets als: dmesg | tail
(Quick translation from the Dutch: block device /dev/sr0 is write
protected will be mounted as read only. mount: invalid/wrong filesystem,
invalid option, missing code page, missing help program, bad superblock
/dev/sr0 or other error... Sometimes more info dmesg | tail:

Because data dvds and commercial dvd's are opening normally I'm at a loss.
Also when I insert a burned video dvd all the time Ubuntu gives message
'cannot mount blank dvd+rw disc location already mounted". I can see the
dvd now in nautilus; I can drag files to it to be burned on it. Offcourse
that's not possible; if I add a file and click on burn to disk Ubuntu
states that there is insufficent free space on the dvd. All burned dvds
are finalized. With mplayer, vlc and totem I tried to access the files on
several dvds but no luck.
In synaptic I found Dvdisaster and tried it. And Dvdisaster was the only
program that 'saw' something on 2 two dvds I tried. It gave the name/title
and was scanning, but that took too long and burned video play in
standalone dvdplayer and windows. Does Dvdiaster use special libraries??
Tried opening dvd from terminal: joost@joost-HP-Compaq-nc6320:~$ mplayer
dvd:// MPlayer2 UNKNOWN (C) 2000-2012 MPlayer Team mplayer: could not
connect to socket mplayer: No such file or directory Failed to open LIRC

Exiting... (End of file)
[Totem in terminal also doesn't work.]
I reinstalled restricted extra's and codecs (reinstalled these: ibdvdcss2
libdvdread4 libdvdcss-dev), with "sudo
/usr/share/doc/libdvdread4/./install-css.sh" and rebooting but to na
avail.
Tried several of the tips here: DVD wont mount Ubuntu 12.04 but no luck.
My regionset output: Current Region Code settings: RPC Phase: II type:
NONE vendor resets available: 4 user controlled changes resets available:
5 drive plays discs from region(s):, mask=0xFF [Don not see a number; but
commercial dvds play normally.]
Is there something that Nero "does" while burning? Do not reckon; because
only playback issues with Ubuntu (13.04). Some regionfree encryption or
something which Nero [also] burned which isn't standard? I'm thinking UDF
support in 13.04, current kernel?? But haven't got a clue.

My issue seems a lot like: Can't Mount a not copy protected DVD Video?
Just ran in to this issue today. But has been a long time since I played
dvd on my laptop, so perhaps old pre-Raring issue. Anyway, need some help
here, been googling and tryin for hours...
Many thanks in advance!
