I have WinXP, SP2. After I installed the Nero 18.104.22.168 update, I tried editing a DVD VR disk. Everything seemed to go well, but on playback, the menu froze. I tried this several times with several disks. The videos can be imported into Nero, but will not play back.
Nero 7 retail box version, and 7.01.2 do not have this problem. Indeed, I was able to create a playable DVD VR disk under those versions of Nero using the same disk and content that failed under 22.214.171.124.
