Problems with new LED Zeppelin DVD?!?!

[DaShiznit]

just wanted to know if anyone has successfully backed up the second disk of the new led zeppelin dvd that was just released like last month ... i am trying to keep all the extras since there is so much good video of the band on there ... the problem is that the two dvd set are both on dual sided dvd disks meaning 9.8 gbs per disk ... the first dvd i had no problem with when i shrunk the video files down with docce4u and put everything back together with scenerist ... the problem lies in the second dvd ... it doesnt seem that there is a reasonable average bitrate to shrink all the extra footage too while making everything fit onto a dvd-r ... and when i tried to make them as small as possible like 800 average each then scenerist seems to always crash when compiling the files back together

just wondering if anyone has successfully backed this second disk up and if so what bitrates you encoded the extras at so that they all fit onto a dvd-r

fyi ... i am not a n00b at backing up dvds ... i have done over 100 successful full backups just like this one ... for some reason scenerist wotn work right ... any help would be appreciated

Thanks
