Ripped DVD to HD with Smartripper.
Removed trailers etc except for the scene selection and the actual movie.
Ifoedit plays the rip and it looks ok.
Write to DVD-RW.
Try it in stand-alone player and the disk spins for a bit and then get a disk error message from the player. Pressing menu on the remote - actual DVD menu then pops up on the screen. Movie and scene selection work.
The player takes DVD-RW as ripped DVD copied to a RW works.
Try the disk in the computer using PowerDVD and everything works fine.
Tried using some DVD test files for PAL and NTSC and they worked without any problems. So it must be a problem with the DVD ifo files.
Using
Ifoedit 0.9, Nero 5.5.8.0

Thanks in advance
