tv_grab_be available days?

Hi,

I was wondering why only 6 days of data can be grabbed?

When I start xmltv tv_grab_be, I get the following info:
getting dates for which listings available: got 11, done.
getting 6 days of listings

I know that by default only 6 days are grabbed, but when I add --days 11, it still only gets 6 days.
I get a message stating that somewhere in /perlapp/... only 6 days are defined.

Can this be changed?

Thanks for the info!!
