Any news over the last 2 months? Shouldn't be so hard for someone with python knowledge to fix the dependencies.

[Jan Schneider (yunosh)]

I think the dependencies are messed up, and in trying to handle that Ubuntu phases out PyXML, ofdb.py was patched incorrectly. This is my patch which got ofdb.py working *without* python-xml

[MarcRandolph (mrand)]

Good timing on asking about this. 12 days ago a related change was made upstream:
http://svn.mythtv.org/trac/ticket/6317

Could you try the updated file (http://svn.mythtv.org/trac/browser/trunk/mythplugins/mythvideo/mythvideo/scripts/ofdb.py?format=txt) and that out and see if it resolves your issue?

[Jan Schneider (yunosh)]

No, it doesn't, because the library paths are still set in the wrong order.
sgmlop.so which is imported from Sgmlop.py only exists in /usr/lib/python2.6/dist-packages/oldxml/_xmlplus/parsers/ on my vanilla mythbuntu system. If the directories are appended to the search path instead of prepended, Sgmlop.py is loaded from /usr/lib/python2.6/dist-packages/_xmlplus/dom/ext/reader/ and thus can't find sgmlop.so.
I'm not a Python guy, but to me the current python distribution looks pretty messed up, with two different xml libraries bundled, one of them incomplete. And I even already removed the 2.5 compatibility libraries which included two more versions.

[MarcRandolph (mrand)]

Howdy Jan, any chance you could check out a 9.10 alpha and see if it is still as messed up? Thanks!

[Jan Schneider (yunosh)]

Unfortunately not, the only suitable machine is in production.

[Jan Schneider (yunosh)]

The paths are still in the wrong order in Karmic. Attached is updated patch.

[Stefan Pappalardo (sjuk)]

After update to Karmic I use tmdb.pl. And I am komfort with it, in the hope that there wil be multilingual netadata grabbing in the future. For me there is no need for ofdb.py anymore.

[Mario Limonciello (superm1)]

We've decided not to include this patch as the direction upstream is to using tmdb.pl. If you'd like to see this patch included, i'd recommend pushing it upstream.
