Hi all,

I have done some tests with the command :
test_sections 20 115

The kernel version is 2.6.3
hw_sections=0

On some mediahighway EPG channels, like these ones, I can't receive the TOT data :
CYFRA EPG:10719:V:S13.0E:27500:160:80:0:0:1:0:0:0
CD EPG:12515:H:S19.2E:22000:160:80:0:0:1:0:0:0
SKY ITALIA EPG:12418:V:S13.0E:27500:161:74:0:0:11702:64511:8600:0

On these ones, I can receive the data :
CSN EPG:12363:V:S19.2E:27500:160:80:0:0:1:0:0:0
CSD EPG:11509:V:S19.2E:22000:160:80:0:0:1:0:0:0

With hw_sections=1, I can receive the data on all the channels.

With the 2.4 kernel and hw_sections=0, it is also working on all the channels.

So I think there is really a problem with 2.6.3 (I have not tested 2.6.1 and 2.6.2).
