Hi,

i have tried to debbuging this, but at the moment without success:(

I have used 3 different cards as 2. or 3. card, and all of them fails in the
same way. After some time (epg-scanning in vdr)  get no more data from the
cards. No more interrupts are handled in this case.

Setting up the filters is ok, so i think something crashed on the cards and
we get no more data in the (card) buffers, or the interrupt handler does not
work anymore in this case.

I have seen sync problems between the frontend threat and the demux thread
also...for example vdr stops all section filter, tune und (re)start the
section filter, but because the demux is much faster then the frontend
threat this result in stopping filters, starting new filter and then tuning
the card (call to fe_set_fontend in the frontend driver). Maybe some invalid
data caused by the tuning during running filters "kills" something in the
driver or at the card.
