This is my "one step" solution:
# Step 1: making fifos
mkfifo fifoaudio fifovideo fifodvd
# Step 2: record time
echo "Put record limit in seconds"
read limit
# Step 3: The great pipe
cat /dev/cxm0|mpeg2desc -a 0 -o fifoaudio -v 0 -o fifovideo </dev/fd/0
> /dev/null|\
mplex -f8 fifoaudio fifovideo -l $limit -o fifodvd|dvdauthor -o dvd -f fifodvd
# Step 4: making TOC
dvdauthor -T -o dvd
# Step 5: burning dvd
growisofs -Z /dev/cd0 -dvd-video dvd
# Step 6: cleaning
rm fifoaudio fifovideo fifodvd
dvddirdel -o dvd

Needs disk sppace, but is the most fast solution that I have found .
For work needs:
