That looks like the "no video stream keep buffering" (no writing) bug..
The first packet is a PSI/PAT..

Try:
 dvbsnoop -if <filename> -s -ts

I use these to parse ffprobe output:

strsearch="\<$ff_aac_latm"
temp_str=`ffprobe -i $thefile 2>&1 | grep  'Audio' | grep $language |
grep $strsearch `
streams_latm_pid=( `echo $temp_str | awk -F'[' '{ print $2 }' | awk
-F']' '{ print$1 }' ` )
streams_latm_index=( `echo $temp_str | awk -F'#0:' '{ print $2 }' | awk
-F'[' '{ print$1 }' ` )

where language="eng" & ff_aac_latm="aac_latm"
