you could try replex -t MPEG2 -z ...
or ProjectX

(if replex fails (crashes), use next time
    dvbstream -n 30 -f 802166 -v 0 -a 6258 -ps -o > file.ps)

also, you can run dvb-mpegtols ts2ps (or just ts2ps) to convert
first to ps and then replex...

also  mencoder -oac copy -ovc copy -o file.avi file.ps
and then  tcextract -x mp2 -i file.avi > file.mp2
could work.
