(redirect to a text file if you need to. dmesg > log.txt, for example) </pre> </blockquote> I cheated and saved both the "pure" dmesg result & the "post mount attempt" result to text files and ran "diff" to see the differences. I tried with both a movie DVD & the install DVD and got the same message each time: ken@Epona:~$ diff dmesg.txt dmesg2.txt 540a541,543 > [ 322.649908] UDF-fs: No VRS found > [ 322.666466] ISO 9660 Extensions: Microsoft Joliet Level 3 > [ 322.713041] ISO 9660 Extensions: RRIP_1991A Actually the install DVD automounted on one occasion, but only once out of about half a dozen attempts. <blockquote cite="mid:48B37E88.1080706@tigershaunt.com" type="cite"> <pre wrap="">Send us everything that was added to the dmesg log from the time the dvd was inserted. </pre> </blockquote> A Google search showed that the "UDF..." line indicates that it's not handling the filesystem type. I've tried variations of the fstab line with "udf"; "iso9660"; and "autofs" but none worked. I'm not sure where to look next. Further searching indicated that the udf kernel module may not be installed, and when I checked it wasn't. However it's not loaded, I've rebooted and it still won't load. The above lines, however, no longer appear in dmesg. I hope all of that might help. See ya, thanks for sticking with it. Ken McLennan Qld, Australia </body> </html>
