Please describe the problem:
1. Filenames changed on burned CD: If i burn some files from a fat32 and some  files from  a ext3 partition, then space characters in filenames are transformed  to "%20"-Strings . The filenames look something unreadable in nautilus. All this happend when i used ubuntu 8.04 and burned simple data-CDs with brasero.

2. Other brasero-problem with burning simple data cds: I can burn files from ext3 or fat32 partitions separately. But the cds with content from ext3-partitions show an other strange behaviour:  This is only visible with the windows explorer [i use ubuntu 8.04 and windows 2000 on my pc]. The windows explorer shows shortend 8.3-filenames like DOS. Nautilus correctly shows the "longer" filenames ... But the feature "increase compatibility with windows systems" is switched on. 

 Is there something wrong with the readability of the cd format?

Best regards,
Bernhard
