[linux-dvb] Re: DVB-S in the US.



Marcus,

   I'll try to find some time today to test per your suggestions
and report back but I'll be climbing the tuxzap learning curve so
it may take a bit(g).  I know I need to install CDK for ntuxzap
and that is where I stalled last, but with specific directions now
I'll have another go!

    Thanks,  Bill
