#3230: Unable to import certain newer DVDs
-----------------------+----------------------------------------------------
 Reporter:  anonymous  |       Owner:  ijr    
     Type:  defect     |      Status:  new    
 Priority:  minor      |   Milestone:  unknown
Component:  mythtv     |     Version:  0.20   
 Severity:  medium     |  
-----------------------+----------------------------------------------------
 When trying to import newer DVD releases, such as ''Stranger Than
 Fiction'' there are a few problems:

 (1) When showing the number of tracks available for import mythdvd reports
 99 tracks available, which I doubt is correct. Several of the tracks have
 the (seemingly) correct length of approximately 2 hours.

 (2) When trying to rip at any other quality than "ISO," the progress
 screen briefly comes up, and then quickly returns to the "hit 0 for new
 import" screen

 (3) When trying to rip at "ISO" quality, the rip continues for a couple of
 minutes and writes between 700MB-800MB to the disk and then suddenly
 crashes back to the "hit 0 for new import" screen.

 I am imported several other DVDs successfully and the hard disk is not
 close to being full. After looking into /var/log/messages on my system
 (Gentoo), I saw these errors:

 The DVD has no visible scratches on it. After doing some Googling, I found
 other DVD rippers having similar problems. Please see:
 http://forum.doom9.org/archive/index.php/t-123124.html

 In summary, this seems to be some sort of purposeful-bad-block scheme, in
 order to prevent users from creating copies of our own DVDs! I have seen
 this problem on another DVD I own, but I can't be sure it is the same
 thing...
