Although you are definitely not a fan of Linux cdrecord builds and works fine here. MANY THANKS ! P.S. It seems to be a great pity that your expertise cannot be used to improve the Linux kernel - probably because of some 'communication problems' as Linus would called it. -- Helmut Jarausch Lehrstuhl fuer Numerische Mathematik Institute of Technology, RWTH Aachen D 52056 Aachen, Germany -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

How is cdrecord-ProDVD different from plain vanilla cdrecord? - It is able to write data CD's in RAW mode because it includes a very fast ECC/EDC lib. - It allows to do clone writing to copy any single session disk. - It includes a DVD recording driver.

Re: Performance problem with 16x audio burns in Linux
From: Anssi Saari [EMAIL PROTECTED] I have a performance problem writing audio discs at 16x in Linux. Cdrecord 1.11a17 can just barely keep its fifo filled during the burn, mostly. Data burns are not a problem, 12x audio burns are also not a problem, or it seems I have barely enough horsepower to manage that, but burning from mp3s with on the fly decoding again has performance problems. Same problem happens when burning video-CDs with cdrdao 1.1.5, 12x fine, 16x problems. Top doesn't show any application taking very much CPU. So you did not enable DMA. You cannot write faster then 12x without DMA.

Re: Performance problem with 16x audio burns in Linux
From: Chris Lawrence [EMAIL PROTECTED] j Try increasing the fifo size to 16m or so (-fs=16m). You may also want to see if you can find a firmware upgrade for the CD-R drive. Also running cdrecord at nice --19 (i.e., -19, not +19) or so will help. You have to do that as root, though.
