I have never set the region on any of my dvd drives, and now am attempting to play a dvd on VLC which fails a third of the way through a 3.5 hr movie. The sr0 drive says "7.6Gb udf". I threw an mplayer command line at it and one of the VOBs a third of the way through says libdvdread chokes on a CSS key. It is a new factory clean commercial DVD, and I have played many others in this drive. It does something similar in a high-end USB DVD writer I have around (which also has no region set--I am a little fussy about doing things that have limited reversibility of change).

So in doing my homework many note that without setting region libdvdcss throws errors (just previously never for me?). Others claim libdvdcss is region agnostic. One thread I read said I need libdvdcss2 but it seems to me libdvd-pkg has "libdvdcss.so.2" . I have a fatdog laptop driving HDMI to a digital surround and big screen for DVDs and would hate to have to get a standalone player for this one disk. Should I compile a newer version of libdvd-pkg?

The current one in Fatdog is version 1.4.2.
The latest one is version 1.4.3, and changes between the two are:

    Squelch potential buffer overflow warning
    
    GCC 7.3 points out that a buffer of size PATH_MAX is being written to
    with data that can theoretically overflow (a string of maximum size
    PATH_MAX plus other constant-size strings).  Fix this by replacing
    sprintf with snprintf.

    CI: added debian, macos, win32 and win64 build jobs.

If you ignore those that starts with "CI" (these aren't real end-user changes), you will see that there is no changes at all; so I don't think updating will help.

From personal anecdotal experience, some DVD refuses (or have problems) reading data if you never set the region. I had one of those drives. They would seem to work - until they didn't. The solution that "fixed it" for me was to set the region __at least once__. It doesn't matter which region you set it to, but you need to set it at least once. Then libdvdcss will work (for all regions).

But don't trust me on this. As I said this is just personal anecdotal experience. Your case may be cmpletely different. Please do your own research before doing it, because as you said - there is a limit on how many times you can set the region.

Thanks for the direction: 1.4.3 is out so I found an ancient half-dead Acer laptop
that drives the stereo around my pool to set region on...same problem in same place.
Sought out actual standalone DVD player in the neighborhood and found disc sputters
and chokes at about the same place (pretty much unwatchable but it doesn't
kick me back to a menu).

Disk is new/spotless; it goes back. Sorry to be an alarmist. I still appreciate
the smart advice...no longer chasing my tail.

Updated: got another new disk as a replacement and issue resolved.
Moral: even when there is no scratch one shouldn't assume there isn't.
