[linux-dvb] Newstruct and DVB-C with QAM_256

[Martin Neuditschko <yosuke.tomoe@gmx.net>]

I have a Hauppauge DVB-c and I used the CVS-snapshot from
02.07.2002 (using:
cvs -d :pserver:anonymous@linuxtv.org:/cvs/linuxtv checkout -rNEWSTRUCT DVB)

If I do "./czap RTL2", I get following output:

Are these values OK? What do the values mean?

Sometimes it is not able to switch to a channel:

Some suggestions to try something?

VOX:810000000:INVERSION_OFF:6900000:FEC_AUTO:QAM_256:2112:2113

What is the difference betweed NVERSION_OFF and NVERSION_ON?
What could I try to use instead of FEC_AUTO?


best regards
