[linux-dvb] Video/Audio Dropouts up to 5sec

["Tobias Faust" <tobias.faust.liste@gmx.de>]

hi,
i have a little problem with the "newest" DVB-drivers (08-11-2003).
Sometimes I?ve got
Video and Audio dropouts up to 5seconds on some channels. For Example:
ARD, Bayern 1(radio), ZDF.
At the first time, i thought the problem is the vdr-software. But now
i think, its the driver (or the signal???? i?ve never changed anything
at the satellite dish or satellite cabels)
I?ve tune the DVB-s card to the  radio channel "Bayern1" and run
femon:

mediabox2:/usr/local/vdr/DVB/apps/szap # ./femon -a0
using '/dev/dvb/adapter0/frontend0'

multiswitch
