Dual Layer DVD's
I just upgraded from Mythtv 0.20 on PCLinuxOS 2007 to MythDora 5.0. The same dvd player (with the same ownership and permissions and same line in fstab) using the same batch of dual layer DVDs will not work now. Burning dual layered dvds is not working with mythachieve or k3b.
Since I haven't used Fedora for a few years, is there something I am missing? My dvd+rw-tools package is current according to yum.
Is dvd+rw-tools broken or do I need a magic feather to make it work?
Any help will be appreciated.
