I have a problem with brasero on my jaunty. When I try to write data on my dvd-r disc, I can't check the option "Leave the disc open to add other files later". It is gray and can't be checked. With Intrepid, I have used exactly those discs from the same box and everything worked just fine, I had the option.

I have tried to put dvd+r disc for burning. This time, I had the option "Leave the disc open...", but the option "use burnproof" was unaccessible.

I always burn discs as Data project, the data is 1.4gb .avi files. Any ideas for a possible solution, please?
