15.04 (Xubuntu, Lubuntu) cannot recognize some DVDs

[Orionds]

I tested this in Xubuntu and Lubuntu 15.04 and then in Xubuntu 14.04.

Xubuntu 14.04 recognized ALL the problem DVDs that 15.04 could not recognize.

I tried using upstart at boot instead of systemd, the problem still persisted in 15.04.

Sometimes, if I reboot using systemd with the DVD already inserted, the DVD is loaded. However, if I eject the DVD and re-insert it, it cannot be recognized again.

However, one or two particularly stubborn DVDs still could not be recognized even with a reboot.

Again, though, 14.04 had no problem recognizing these "stubborn" DVDs.

I have tested, so far, about 30 original DVDs. 4 or 5 showed this problem in 15.04. Xubuntu 14.04 had no problems with these 4 or 5.

I first posted this problem in the Ubuntu forums and at least one other user experienced the same problem (including flash drive recognition problems - I did not test this and, for me, no problems to date).

I forgot to add the following:

I have the latest version of libdvdread4 installed.

I ran the install-css.sh script in all instances.

I also installed the xubuntu or lubuntu restricted extras.

No problems in 14.04 but not 15.04.

If this is still an issue with a recent version, please provide a sample of a failing DVD.
