"
I burn MP3-files. To use the CD/DVD also with MS-Windows I use the option "Increase compatibility with Windows". Brasero cuts the length of every filename to 64 characters correctly.
Addionally I use the plugin "file integrity check" and brasero creates the hidden file .checksum.md5 on the CD/DVD. But the integrity check stops with an error because Brasero ist not able to find the some files.
What I saw is that Brasero saves the original long (!) filenames (> 64 char.) in the .checksum.md5-file but on the CD/DVD there are of course only the short filenames (< 64 char.) available.
To work fine Brasero should save the short (!) filenames (< 64 char.) in .checksum.md5. In other words: For a working "file integrity check" the filenames on the CD/DVD must be the same as in the .checksum.md5-file."

"I tested a little bit and found out:

1) When you only burn one single file, the "file integrity check" always works fine (even if you use the option "Increase compatibility with Windows" and Brasero cuts the filename to less than 64 characters).

2) When you burn two ore more files and - using the option "Increase compatibility with Windows" - brasero cuts the filename of one or more files to less than 64 characters, the "file integrity check" always stops with an error as described in the Bug Description above.

Here is an example:

I burn these two files with the option "Increase compatibility with Windows". The original filenames are:
01_-_This_is_a_test_file_to_look_if_brasero_is_able_to_check_the_file_integrity_of_filenames_with_less_than_64_characters.mp3
02_-_This_is_a_test_file.mp3

On the CD/DVD the filenames are:
01_-_This_is_a_test_file_to_look_if_brasero_is_able_to_check.mp3
02_-_This_is_a_test_file.mp3

As you can see, Brasero cuts the filename of the first file correctly after 64 characters.

The entries in the .checksum.md5 are:
51a31a66cc5eb5110f5bdf41aab0dd87 02_-_This_is_a_test_file.mp3
51a31a66cc5eb5110f5bdf41aab0dd87 01_-_This_is_a_test_file_to_look_if_brasero_is_able_to_check_the_file_integrity_of_filenames_with_less_than_64_characters.mp3

The last rows in the log file say:
BraseroChecksumFiles Getting file /02_-_This_is_a_test_file.mp3

As you can see, the "file integrity check" is searching the file 01_-_This_is_a_test_file_to_look_if_brasero_is_able_to_check_the_file_integrity_of_filenames_with_less_than_64_characters.mp3 but doesn't find it because the filename on the CD/DVD is only 01_-_This_is_a_test_file_to_look_if_brasero_is_able_to_check.mp3.

I also made a screenshot of the error-message but it's in german (see attachment). I try to translate:
"The file integrity check can not be carried out. File "01_-_This_is_a_test_file_to_look_if_brasero_is_able_to_check_the_file_integrity_of_filenames_with_less_than_64_characters.mp3" can not be opend".

I hope this example will help to find the bug."
