ok, read "write a dvb (the linux api) wrapper using the dektec API".
: )

I was talking about using the dvb api, that would be nice to have for the 
dektec cards.
of course, you can get the data using a pipe.

one can do:

create a named pipe:
# mkfifo fifo.ts

# run dvbsnoop:
dvbsnoop -s ts -if fifo.ts

# feed the fifo
DtRecord fifo.ts

bye,
rafael diniz
