I just use dvbtune or dvbstream and that works fine.

As said, I use dvbstream and when it works, *traffic* only receives
packets as long dvbstream is running.

That doesn't seem to happens. My drivers are btw 1-2 month old. My card
is a premium card.

It does. If any output is ever created, then it seems to continue, otherwise
it just reads 50-1800 packets and then waits/hang on a read().

I think this was VIVA on 19E (dvbtune  -f 12670000 -p V -s 22000 -v 309 -a 310)
