is there a reason for the whitespace?

msgid "Brasero Disc Burner"
msgstr "Vypalovací software Brasero"

is there a reason to use two different strings?

#: ../data/brasero.schemas.in.h:8
msgid "Enable immed flag with cdrecord"

maybe set "immed" into "" ?


Any schema strings that are boolean:

msgid ""

can these be synced?

why not capitalized?

msgid "Do you want to add a \"%s\" which is a video file?"

I don't get this. Since when do I say "a videoname.mpeg"?

msgid "loading"

why not capitalized? Does this really have to be marked as translatable?

msgid "it will be removed from the project."

Capitalize, please.

#: ../src/brasero-blank-dialog.c:222
msgid "Error Blanking:"

Is "Error blanking" a function name? Or was there an error while blanking? -> Translator comment

#: ../src/brasero-blank-dialog.c:268
msgid "the disc is ready for use."

Capitalize?

#: ../src/brasero-blank-dialog.c:367

Verb, noun? -> Translator comment

Uargh... CAPITALIZE!!!

could these (and MiB, GiB) be merged, if i look at the code...?

Discs themselves cannot be busy.

Capitalization......
And can you please split "Do you want to continue anyway?" to a seperate string so it does not have to be retranslated all the time?

#: ../src/brasero-data-disc.c:1051
msgid "_Don't replace"
In general: All these "Don't", "won't", "can't" aren't proper english.
In this case I'd rather use "Keep" instead of "Don't replace | Replace" - makes it clearer (with a translator comment)

"NOTE: such a file hierarchy is known to work on linux."

"Don't" is ugly. And just negating is ugly to. Use buttons that speak, otherwise we can get back to the old Yes/No scheme from MS Windows.
