Hmm, don't know what you mean. TS_PAYLOAD_ONLY is defined in the 
internal header files, it's not part of the public API. I should move 
demux.h into the driver directory.

If you want to get a TS you have to read from the dvr filedescriptor 
while the demux fd is still open. As alternative you can get PES packets 
from the demux filedescriptor when you set the output to memory.

I extended szap to route the stream to the dvr device last days, I can 
commit this now as example. Call

$ ./szap -r n-tv

in one console and let it run, then

$ cat /dev/dvb/adapter0/dvr0 > /tmp/stream.ts

in another console to save the transport stream. Later you can use the 
mpegtools to convert this into a program stream.

hope this helps,

Holger
