brasero can't copy movie DVD on x64 installation

Funny, after copying the mentioned DVD on the 32 bit system, I tried another DVD on it and now it brings up the same complaint.

I forgot before to attach the screenshot. Here is the one from the 32 bit system.

Is there some diagnostic utility that can tell if a DVD is copy protected ?
Or other suggestions to clear up this issue ?

Thanks for your report, could you run brasero from the command line as: brasero --brasero-media-debug --debug &> brasero-debug.txt perform the operation to reproduce the bug and attach the resulting file to the report?. Thanks in advance

here it is.

I tried the same DVD in another PC, running Ubuntu 9.04 x86 (32 bit), brasero 2.26.1-0ubuntu1.
There it works fine, the debug output is attached.

Thank you for taking the time to report this bug and helping to make Ubuntu better. A new version of brasero is available in both Lucid and Maverick and we are wondering if this is still reproducible in any of those versions, May you please test and give us of feedback about it? Thanks in advance.
