looks fine. Use:

$ szap -r <channel>

to set up the filters for recording through the DVR device. Then, while 
you keep szap running in another console type:

$ cat /dev/dvb/adapter0/dvr0 | ts2ps | mplayer -

that's all. ts2ps is part of the mpegtools and converts the transport 
stream to a program stream. New (CVS?) versions of mplayer can process 
transport streams directly, there are also DVB plugins and patches 
floating around on the web, just google a little around...
