i commented out those lines and reran mythfilldatabase.
the long delay after:
CoreContext filldata.cpp:421 (GrabData) - ------------------ End of
XMLTV output ------------------
is now gone so i think those lines is the source of the slowdowns.
of course since i commented out those lines it it now needs to update
every single program there is so on first run it spams the database
quite a lot but overall it still is quicker.
i'll restore those lines since i don't want inetrefs to get screwed up.
