[Bug 42023] Re: Erros on writing and reading a dvd-ram

[tlutz]

I just installed Gutsy, and I think I may have a similar problem.  Upon
inserting a burnt DVD (burnt using Nero in WinXP), I received the
following errors:

[13150.597572] UDF-fs: No VRS found

I had to eject and remount about 5 times to get it to read properly.
When it finally did mount, I copied the files to my hard disk.  From the
point of mounting to the end of copying, I recorded the following
messages from dmesg:

While the disc would not mount properly in Ubuntu, it mounted fine in
Windows XP through VMWare and I was able to read files off of it.
