Hmm, I still not convinced that this is a type-of-CDR(W)-media issue. The scsi device reports a sense key for a medium error, but not because the medium has caused a failure; there are simply not enough different sense keys for more precise error information. Therefore an an Additional Sense Key (ASC) and Additional Sense Key Qualifier (ASCQ) are used to describe the error condition precisely. Use the -v switch for cdrecord and watch the buffer status while burning a CDR at a higer speed. If it runs empty, there's your problem. If not and you still get 'loss of streaming' errors, watch for reports regarding scsi transport in /var/log/messages or dmesg(8). -Bj=F6rn To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
