I'm marking the bug as invalid. Turns out that mytharchive's importing and exporting is version specific. See comment from mythtv.org below.
To anyone encountering the same problem that I did, I found that temporarily changing the database recordedmarkup column name from data to offset, and replacing offset="" entries in the mytharchive .xml files with offset="NULL", allowed me to import the recordings properly to the new version. Regards, David This was the reply posted at MythTV: MythArchive, and MythTV, in general, do not support importing data from previous DB schema versions. You must import MythArchive native exports (and restore mythconverg backups) into the same DB schema version from which they were created. Therefore, exports from 0.21-fixes are not compatible with 0.22 fixes. The proper procedure to make sure the exported programs were brought over after upgrade to 0.22-fixes would have been to import them into 0.21-fixes, then back up the database, then upgrade to 0.22-fixes and let MythTV's database upgrade convert the data. If you have questions on proper upgrade procedure, please ask for more information on the mythtv- users list. There is hope to one day make a real export format that's not version specific, but at this point, it's just a feature request/item on some TODO lists. ** Changed in: mythbuntu Status: New => Invalid ** Changed in: mythbuntu Assignee: (unassigned) => DJ Dallas (djdallas) -- Mytharchive (myth 0.22 karmic) fails to import/export recordedmarkup https://bugs.launchpad.net/bugs/486233 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
