SamyGO

Try and see
We didn't test it before. Unfortunately, my DVDRW Drive is broken.
TV can play DVD's vob files if they are decrypted.
But you needed to play each vob file manually.

Hi antartide,

I just tried it on my UE40B7020, FW 2008, with SamyGO patch.
NEC 2500 DVD drive (yes, an old one) inside a conceptronic housing (equally old).

Tough luck, the usb-drive is not recognized. Not with a data CD inside, nor an encrypted movie DVD.

So maybe it's the combination of TV and FW, but I doubt if this will work on any other type of tv.

grtz,

I think problem is absence of iso9660 kernel module support for mounting CDROM.
We needed to mount DVD via shell. After we can say if it works or not.
Also we needed to mount that DVD's sub directory to FAT USB (might be virtual USB) because exeDSP does not recognize fisle system if it's not FAT, NTFS or EXT3...

Hi erdem,

You are absolutely right.
Can't mount a polycarbonate disk without isofs support.

grtz.

I got curious, so i did some tests with external DVD writer (SE-S084) and my B650 TV.
I compiled required kernel modules from samsung sources (sg, cdrom, sr_mod, isofs, udf),
created missing /dev/ files, etc. After that DVD got recognized properly by kernel:
Pretty much everything seems to work just fine:

1) mount -t iso /dev/sr0 ..., mount -t udf /dev/sr0..
2) cd audio ripping (tested with icedax from debian armel repository),
3) cd/dvd burning - successfully burned dvd+r disc with wodim (debian armel again)
4) mounting .iso images via loopback is possible, with loop.ko module loaded.
5) cd audio play/stop/pause/eject controls - working (probably, no headphone jack
in my burner to confirm this).

Not surprisingly, manually mounted ISOs/UDFs are not recognized by exeDSP / media player
- maybe it's doable, maybe not..

Nevertheless, I think support for scrambled commercial DVDs will be most likely out of the question.

After mount, create empty folder at your USB FLASH drive, than mount your DVDROM's movie directory which have VOB files or your DVDRoot directory to this flash devices folder.
This way, you can see your DVD ingredients. Try to play VOB file...
Anyway, you don't have to mount your DVDD directly to TV, you can make same thing via NFS too. But your setup is more exotic to the eye

Yes, thank you - it works, files on CD/DVD are indeed playable in Media Player.

Nah, not really I use network shares myself, and I don't even own aforementioned external dvd burner - just borrowed it temoprarily to perform same tests.

So, we do know that it actually works. No user interface though, for disc mounting/unmounting - i don't know, maybe it will be beneficial for some people out there, to include such features in some future samygo all extensions releases

Kernel modules attached - tested on LE37B650 T2W with T-CHL7DEUC-2005.0 firmware.

[EDIT] Attachement removed (quota restrictions exceeded). If someone still needs those modules, I belive they are readily availlable in SamyGO sourceforge repository.

Is the DVD is protected with protection algorithm? I will try to mount iso image from NFS with your kernel modules...
