Are you sure? Imho DVD-Ram runs some checking cycles during the recording, thus recording is slower and more secure. (Anyway, I like DVD-Ram because it can be used as an ordinary block-device, like a hd ;) ok. But what may have gone wrong? Is it a media-error or do I do have to upgrade firmware or are there any known linux-kernel issues? I cannot imaging, that storing a disc in a shelf in its Jewel-Case cause damage to the disc. However, the writing cycle four months ago have not shown any problems... Keep smiling yanosz
