I have read that szap -r -p options was broken. May be is it reason of your problem with the latest MPlayer ?

could you try please to play in another way - after of tine with szap2 help please try like this 

dvbsnoop -s ts -b -tsraw | mplayer -
dvbsnoop -s ts -b -tsraw | xine stdin://


dvbstream -o 8192 | xine stdin://
dvbstream -o 8192 | mplayer -
