Hello,

I'm trying to make my TTC2300 work with linux and have achieved some 
success so far (I think?)
as my messages from dmesg and czap below shows.

But after that things ground to a halt, I cannot get an image to display 
no matter what...

Downloaded & compiled dvbstream 0.6 and got this when trying to grab a 
previously czapped channel

dvb:~/dvbstream/dvbstream# ./dvbstream -f 378000000 -s 6875000 -qam 64 
-v 4386 -a 1074 | mplayer -
dvbstream v0.6 - (C) Dave Chapman 2001-2004
Released under the GPL.
Latest version available from http://www.linuxstb.org/
Tuning to 378000000 Hz
Using DVB card "ST STV0297 DVB-C", freq=378000000
tuning DVB-C to 378000000, srate=-1714934592
Getting frontend status

and the tuned symbol rate value (srate) above doesn' t look like my 
supplied 6875000 at all....

Any suggestions more than welcome!

Thanks in advance
