Apply the patch to scan..
You will get an additional option to scan (-h)...

This will give you the PMT PID in channels.conf. Temporarily rename this 
channels.conf as for example, channels_pmt.conf or something else.

I have not made a patch for szap to accept PMT PID in it's config. Therefore 
temporarily you have to scan again without the (-h) option, to get the the 
standard channels.conf.

Use szap to szap to your channel... You should see the normal FE_LOCK, You 
could give the -r option also to szap.



Use the utility (i named this as ca_zap, this doesn't do any zapping but is a 
very simple PMT parser and converts to EN50221 format and sends the parsed 
data in EN50221 format to the driver.

The utility takes in 2 parameters, ie the channels.conf file with the PMT_PID 
and the channel name.


ie, for example 
ca_zap channels_pmt.conf "Channel name in channels_pmt.conf"
You will see the descriptors parsed and sent to the driver if you are in 
verbose/debug mode.


After this you can try out a simple test.

In the dvb-apps/test, you have 
test_dvr

It takes in parameters test_dvr output_file PID's.

You can just pipe the output to mplayer with a cache

for example...

 ./test_dvr /dev/stdout 282 516 654 | mplayer -cache 2048 - 
is what i did...

You should see your encrypted channel with mplayer.
