The only possible explanation for this phenomena I can think of is that unit remains under some auto-play/mount facility control. If this is the case, then the performance drops because the unit is periodically polled by opening corresponding /dev/dvd, which results in query for table of contents (this is the way Linux kernel is). One can wonder how come DVD+R is affected, but not DVD+RW. Well, DVD+RW TOC is not changed during recording, while DVD+R TOC is. Query for DVD+R TOC most likely results in buffer purge, which limits the performance. A. A. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
