  • Status changed from new to infoneeded_new

Since you specify that it works in Windows, what about mplayer, xine, and vlc or Linux? Disney/Pixar? DVDs are usually protected with ArcOSS/bad block insertion, and the DVD Nav Packet read failed stuff suggests that that might be at issue here.

Has this disc ever worked in Myth?

This excerpt plays for me under 64-bit fedora 12, with vlc and with 0.23-fixes. HTH

This ISO used to work in Myth, but I can't say how long ago. Under linux, mplayer and vlc both work; xine complains about not finding a demuxer plugin.

Jim - the attached hack should get this working temporarily. Still trying to figure out a simple approach to fix this that does not involve re-opening the disc again for the 99% that do work.

Can you confirm you see the same problem with the full ISO? I was hoping this had been fixed with some of the recent dvd playback changes, but still no joy.

I'm still seeing the problem with the original main title ISO rip. The dvd-reset.diff patch still makes it work.

  • Resolution set to fixed
  • Status changed from infoneeded to closed

DVD startup fixes.

  • re-implement the dvdnav_first_play method that Stanley Skamithi added

some time ago and I removed some time later...

  • minor tidy up of the CloseDVD method.
  • use the dvdnav_first_play call when 're-starting' the dvd following

the codec scan.

Closes #9143
