Oliver,

This does not work.

I have launch gnutv like this: 'gnutv -adapter 0 -channels hb.conf -out
dvr -timeout 30 TF1'

Then on dd

tv@tv:~> dd if=188 if=/dev/dvb/adapter0/dvr0 of=/dev/dvb/adapter0/caio0
^C36071+1 records in
36071+0 records out
18468352 bytes (18 MB) copied, 76.4947 s, 241 kB/s


And another dd

tv@tv:~> dd bs=188 if=/dev/dvb/adapter0/caio0 of=test.mpeg
^Cdd: reading `/dev/dvb/adapter0/caio0': Resource temporarily unavailable
1338880+0 records in
1338880+0 records out
251709440 bytes (252 MB) copied, 34.3276 s, 7.3 MB/s
dd: closing input file `/dev/dvb/adapter0/caio0': Bad file descriptor


The first dd reports a more/less correct size for 30sec of encrypted tv
~ 18MB.
But the 2nd dd shows a big generated file out of the device. Plus it
mostly contains the following pattern : lots of FF separated by 47 1F FF 10.

I hope you can guide me to solve this - it is getting painful. Can we
review the code together ? The starting point should be the
ts_write/read methods.
