Well, no - *.vob files are not playable from scrambled DVD ("Not supported media format").
Works just fine with vob files on unprotected / home made DVDs..
For really desperate (and really patient) people, it may be kinda possible to 'backup' DVDs entirely on TV, to USB/network drive, and then watch decrypted VOBs in Media Player. At least in theory..
Tested it with 'dvdbackup' from debian repository (with necessary libraries). Actually works, it's just little slow when executed on TV tiny CPU
It took ca 35 minutes to descramble my 12 Monkeys (~7.5GB) DVD on TV.
It was fun
, but seriously, it' s just completely impractical.

Can you write,please, the procedure step to step for mounting external device?
(many are new of linux world =D)
So i have a dvd player and i want to see the avi files on it, how i can?
I'm not very good at HOWTO-writing (and my english really sucks)..
Anyway, here is quick & dirty script I used (assuming 'cddvd-samsung-modules.tar.gz' archive contents were unpacked to '/modules' directory od the 1st USB drive):
Code: Select all
cd /dtv/usb/sda1/modules
insmod drivers/scsi/sg.ko
insmod drivers/cdrom/cdrom.ko
insmod drivers/scsi/sr_mod.ko
insmod fs/isofs/isofs.ko
insmod fs/udf/udf.ko
cd /dtv
mkdir devices
mknod devices/sr0 -m 0660 b 11 0
## for icedax
export CDDA_DEVICE=/dtv/devices/sr0
Then you need to mount disc content in some directory accessible by Media Player, eg:
Code: Select all
# mkdir /dtv/usb/sda1/dvr-mount
# mount -t iso9660 /dtv/devices/sr0 /dtv/usb/sda1/dvr-mount
(or 'mount -t udf ...', depending on the disc format); you may try just
Code: Select all
# mount /dtv/devices/sr0 /dtv/usb/sda1/dvr-mount
and hopefully system will be able to guess filesystem type correctly.
Files from CD/DVD should be now visible in 'dvr-mount' directory, while browsing USB drive in Media Player.

And how i can compiled required kernel modules from samsung sources?
Sorry my newbee questions =D!
Yes all dropped...
You needed to cross compile tool chain for compile that modules.
It's easy to build one from SamyGO OpenEmbedded SVN

I think that modules for CI device, not CI+.
You needed to compile required libraries for CI+ series.

Code: Select all
mount: Mounting /dtv/devices/sr0 on /dtv/usb/sda/dvr-mount failed: No such device or address
I think that's because mount point is in FAT32/VFAT filesystem; try to mount in e.g. /dtv/dvr-mount.
Is it possible to get all modules for CI+ device, needed for CD/DVD-USB mount?
Unless I'm very much mistaken, there are freshly compiled dvd/cd/iso/udf related modules in recently updated Samygo Extensions (in this thread:
http://forum.samygo.tv/viewtopic.php?f=5&t=96), maybe you can have better luck with new versions.

i didn't realized this thread till now, so scsi and cdrom driver aren't included. just some filesystem driver.
