The only change that you should be bothered with should be about the TS
packet length,
just revert this one line from Marko 's patch (for your 1034 DVB-S)

-		(mantis->ts_size ? dvb_dmx_swfilter_204: dvb_dmx_swfilter)
+		(mantis->ts_size ? dvb_dmx_swfilter: dvb_dmx_swfilter_204)

and you are a  winner.
