why on earth are you running mplayer dvb://  alongside tzap? there's no 
reason.
tzap is needed to tune the channel and stream its content to the 
appropriare dvr0 device,
mplayer when run with the dvb:// syntax does the same thing so
1) either run only mplayer dvb://
2) or run

tzap -r -c .tzap/channels.conf CTS

and on a different terminal run mplayer<  /dev/dvb/adapter0/dvr0
