tv_grab_nl as found in xmltv-grabbers-0.5.39-59.rhfc3.at.rpm is a bit broken, it throws several errors, it missed the rename of ¨VRT TV1¨, but for the rest it works. tvgrab_nl_wolf is in worse shape, the output seems to confuse freevo, claiming no channel info is available.
You might want to try grab_tv_nl_gert from http://xmltv.assies.info/dist/. More info about grab_tv_nl_gert at http://www.addictivesoftware.net/index.php?option=content&task=view&id=3&Itemid=28.
Now there are two ways to get your TV.xml in place:
tv_grab_nl > /tmp/TV.xml
(possibly as nightly cronjob)
or configure local_conf.pyto use the grabber of your choice:
XMLTV_GRABBER = 'tv_grab_nl'
and then call
to update your program info.
