Hi, i am participating in this discussion because i am very interested in the technical reason of Tomasz' problem. After all the DVD code of libburn is inspired by the code in dvd+rw-tools.

It might be interesting to see what happens if speed is set to -speed=6 explicitely. In a second experiment -speed=8 could be interesing, too. Another experiment would be to use my program cdrskin which is based on libburn. Home: http://scdbackup.sourceforge.net/cdrskin_eng.html Source: http://scdbackup.sourceforge.net/cdrskin-0.4.2.pl00.tar.gz Binary: http://scdbackup.sourceforge.net/cdrskin_0.4.2.pl00-x86-suse9_0-static.tar.gz It is to be operated like cdrecord. As said, libburn's understanding of MMC DVD specs is quite similar as in growisofs. Nevertheless it is different code which i derived from hints of growisofs and from reading MMC-5 specs. So if it shows no speed decay then we would have good chances to find the decisive difference. On the other hand, if the slowdown occurs with cdrskin as with growisofs then we would have to compare our command sequences with those of cdrecord (option -V if i remember right). Regrettably i got not much chance to purchase 8x DVD+RW. One of my drives would be able to write them (TSSTcorp CDDVDW SH-S203B). Have a nice day :) Thomas -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
