[SOLVED] Failing to read DVDs in 0.31

[cliveb]

I recently built a new 0.31 system, and things are generally going well.
Today I attached an external DVD drive and when attempting to play a DVD get the error "Could not read first 2048 bytes".
The frontend log includes these three lines repeated over & over until eventually it gives up:

Code: Select all

2020-11-26 10:40:35.164250 E [16596/16596] CoreContext DVD/dvdringbuffer.cpp:713 (safe_read) - DVDRB: Failed to read block: Error reading NAV packet.

I've tried different disks, different USB cables, connecting directly and via a powered USB hub. This new 0.31 system is on a Raspberry Pi4.
Playing DVDs using the same external drive works just fine on my existing 0.27 system on an old Acer Revo 3700.

Is there some configuration issue I've missed?

Wouldn't be due to a lack of libdvdcss would it?

Indeed it would. Thanks, DVD playback is now working.
Now you mention it, I do vaguely recall having to add it on the 0.27 system, but it was so long ago I forgot about it!

Glad I could be of help.

If you're happy with the fix could you possibly added [Solved] to the subject line in the first post?

Ta.
