i tried to tune to the channel with czap and record with ts2ps after this but
the size of the resulting file is also 0 bytes.
Also unloading the dvb modules and reloading them does not help only rebooting
helps.
could this problem cause by mythtv holding the card "opend" without recording
for a long time? This problem will not appear when i stop the mythtv-backend
just after a reboot, wait 2 hours and than start myth-backend and record
directly.
