[linux-dvb] Filter limitations on fullfeatured TT card?

[Josef Wolf <jw@raven.inka.de>]

Hi!

After setting up 16 filters with DMX_SET_PES_FILTER, I get "Device or
resource busy" error when I try to set up the 17th filter.  I notice this
problem only on the first card (adapter0), which is a full-featured one.
The other three (budget) cards in the same box accept as much filters as
I try to set.

I have not noticed this problem before.  It was working as expected for
the last two weeks without reboots.  But after I rebooted the box today, 
I noticed the above mentioned problem.  Shutting off for a couple of hours
to let the card cool down did not help.

Here are some infos which might be of interest:

Any ideas what might be the cause?
