I'am trying to get my TechnoTrend C1501 dvb-c tuner card work under 
fedora 12. While at it i ran in to a error of czap.

czap -c ~/.czap/czap-final.txt "Nederland 1"
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
  84 Nederland 1:388000000:INVERSION_AUTO:6875000:FEC_NONE:QAM_64:88:89:8004
ERROR: cannot parse service data

At the v4l-dvb mailing list i got the following awnser:

[quote]
The czap utility (dvb-apps/util/szap/czap.c) cannot scan the channel
configuration file when compiled on Fedora 12 with gcc-4.4.2.
Problem is tha the "sscanf" function uses the "%a[^:]" format
specifier. According to "man sscanf" you need to define _GNU_SOURCE if
you want this to work because it is a gnu-only extension.
Adding a first line "#define _GNU_SOURCE" to czap.c and recompiling
solves the problem.

I guess I should be using tzap not czap.
Seems to working now.
