MythDVD Import Error (Possibly libdvdread3 or libdvdcss2 problem)

[Rob Frawley <robfrawley@…>]

Summery

This issue is not a blanket issue as some DVDs import fine. This has happened to me with a few DVDs, most recently The Prestige. From the standpoint of MythDVD (the graphical interface), the time remaining continually increases to extremely high numbers, and subsequently never finishes.

This issue appears to be related to retrieving the table of contents from the DVD. It seems MTD thinks every chapter is 0 seconds long.

The below output occurs when I try to rip the DVD using the "Perfect" setting.

Also, if you actually try to start the ripping process, mtd outputs the following:

Closing Notes

It is important to note that trying to rip an ISO image of this DVD results in a read/write error from mtd.

[Rob Frawley <robfrawley@…>]

I figure it might be important to know the versions of libdvd* packages installed:

dpkg -l | grep libdvd output

ii  libdvdcss2                                 1.2.5-1                              a portable abstraction library for DVD decry
ii  libdvdnav4                                 0.1.10-0.2                           The DVD navigation library

mtd makes no attempt to bypass copy protection, it never will.
