For generate my ~/.dvbrc file, I first wrote a ~/.dvbrc-transponders file, 
where I put my transponders configuration :
LNB ID 1 TYPE 3
  SAT ID 1 NAME "DVBT-TDF-CCETT" LNBID 1 FMIN 650000000 FMAX 794000000
    TRANSPONDER ID 1 SATID 1 TYPE 3 FREQ 706000000 BANDWIDTH 0 GUARD_INTERVAL 
0 HIERARCHY 0 HP_RATE 2 LP_RATE 1 MODULATION 3 TRANSCRIPTION_MODE 3
    TRANSPONDER ID 2 SATID 1 TYPE 3 FREQ 794000000 ...
I found values reading my ~/.tzap/channels.conf file and I converted them 
according to /usr/src/linux/include/linux/dvb/frontend.h structures (0 stands 
for the first element of each enum, 1 for the second, ...). I don't know if 
there is a more simple way to do it.
Then I used the "satscan" application from libdvb package to generate the 
channels configuration :
satscan -ni ~/.dvbrc-transponders > ~/.dvbrc

I'm using a Mandrake too (kernel 2.6.3-7mdk), and it works very well.

You can use dvr device with
"tzap -r channel"
and "xine stdin://mpeg2 < /dev/dvb/adapter0/dvr0"
or "mplayer - < /dev/dvb/adapter0/dvr0"
(mandrake/plf original versions of xine and mplayer).

Or video4linux device with
"tzap channel"
and "XawTV -remote -c /dev/v4l/video0" (I don't know how to activate sound).

xine also suports DVB directly : "xine dvb://"

For VLS, see http://www.via.ecp.fr/via/ml/streaming/200312/msg00025.html
I hope I will manage to get it work next week ;)

Good luck ;-)
