Just recently upgraded Xubuntu 12.10 after having installed 12.04 originally. Ever since that happened, any time I inserted a disk into my DVD/CD reader/writer I would end up getting a number of error messages from my DVD player/Audio player softer, typically with any of them either crashing or returning a GStreamer backend error.
So doing some research I tried to mount it manually, and it typically returned the error messages you'll see below: (using the dmesg | grep "sr0" command)
[17545.435584] end_request: I/O error, dev sr0, sector 0
[17545.492968] sr 3:0:0:0: >[sr0]
[17545.492981] sr 3:0:0:0: >[sr0]

[17545.493003] sr 3:0:0:0: >[sr0] CDB:

[17545.611568] FAT-fs (sr0): unable to read boot sector
When I grepped this, the number of error messages just seemed to spill all over the screen, and typically all revolve around the I/O error.
I then went into VLC and tried to run the stuff through there, but for some reason it won't read with the default devices. Instead I have to manually input sr0 into each of the /dev/ references and it will play just fine, until I exit out of the program, at which point I have to re-input everything.
I have already installed all the media dependencies, both open source and restricted, through the software center.
I just found this strange, as out of the box 12.04 there wasn't any problem what so ever.
At this point, it could be that all my audio CD's are not in a format that is familiar with the OS (I've read in some places that EXTF4 has issues with this) but I don't see how that could be a problem when the above error messages even tested to see if it is EXT3 as well?
I've tried my best to troubleshoot this up till now using existing topics, but it seems that this is a regular problem with a multitude of varying factors that incorporate into it, including but not limited to read/write problems with the format of the CD and right protection.
Is there something integral that I am missing?
