> Hi, I am new to MythTV.  I have set up a backend and frontend.  I am installing on Debian (7.3) and using deb-multimedia's version of .27.  most functions seem to work very well on the frontend, i am able to stream from the backend live tv as well as recorded shows.  one thing that does not work is playing dvd's and blueray's.  I have googled and checked the suggestions I have found.  for example, there is a /dev/dvd linked to /dev/sr0.  also, there is a /media/cdrom that contains the bluray when inserted.  I am using nvidia drivers (current) with a geforce 630 hdmi to my stereo.  audio and video are fine when streaming from the backend.  here is some info that might be helpful.

Alsa permissions error in there as well..
BD playback via the videoLAN libraries etc only works up to mkb v28.
MakeMKV provides good (integrated) solns for later discs.

DVD playback messages should have mentioned libdvdcss ?
Try Handbrake to debug DVD access.
