Everyone:
Does anyone here have experience using the program "regionset" to change
the region code on a DVD player?
Specifically, has anyone tried to make a drive region-free (region code
0)? And if so, with what result?
The problem: I have a boxed set of DVD's, 12 in all, from Region 2. I
live in Region 1. A few versions of Fedora back (probably F21 or F22), I
found I could play back those Region 2 disks without a problem. But now
with F26, playback even on the "vlc" program gives me sound, but no
picture--a black screen. Dragon refuses to play them at all. The makemkv
program takes about ten minutes trying to do a workaround with the
region codes not matching. Then it seems to work, but the output files
all have sound (including all sound tracks if it has more than one), but
no picture.
Sound, video and subtitles are all muxed together on a DVD so if you
have sound it is breaking the CSS Access Protection just fine. Looks
like you have a problem with a missing mpeg2 video codec or something of
that nature. Linux DVD playback software still isn't able to use the
CSS stuff in the drive the right way, it ignores the region codes
entirely and libdecss simply breaks the encryption thanks to DVD Jon's
efforts in cracking the crypto and giving the break to the world.
(Which is why Fedora will probably never ship that particular library.)
Try mplayer from a command line and see what it has to say, verbose is
of course best. IF it sees the video but can't find a codec or can't
get the display drivers right it will point you to what needs
troubleshooting.
I don't know how to use mplayer from the command line. I shudder to
think of how many switches and parameters I have to specify. Can you
help with that?
