If I generate an iso image using mkisofs from genisoimage-1.1.16 with rock ridge and joliet extensions and burn it on a DVD, the DVD is unreadable in Windows. Windows just tells me that the DVD is corrupted. Reverting back to genisoimage-1.1.12 fixes the problem. I'm running f7 on x86_64. Where do I bugzilla this? I can't find genisoimage on the component list. I figured this out after having burned 22 DVD's... :-( :-( :-( Mogens -- Mogens Kjaer, Carlsberg A/S, Computer Department Gamle Carlsberg Vej 10, DK-2500 Valby, Denmark Phone: +45 33 27 53 25, Fax: +45 33 27 47 08 Email: mk@xxxxxx Homepage: http://www.crc.dk
