Description of your issue, suggested solution and other information

downloads from orf tvthek do not work any more; old urls went away server-side (500), and the new ones give the above errors. it is not sufficient to just change the "program" regexp part in orf.py to "profile", that results in an error about "Unable to extract segments".
