Things are getting seriously unreal. I just built DVB (from 
:pserver:anonymous@linuxtv.org:/cvs/linuxtv) and dvbtune (from 
:pserver:anonymous@cvs.dvbtools.sourceforge.net:/cvsroot/dvbtools) on a brand 
new machine (Pentium III 1.2GHz) with a brand new kernel (2.4.19) -- and I 
get this error sometimes. Other times I get a channel listing, but it varies 
from try to try, and sometimes I just get 'nothing to read from...'

It's a similar story when I try to use dvbstream. Tuning to BBC1 I don't get 
any data unless I use both the -qam 16 and -cr 3_4 flags. These cause the 
reported error rate to go from about 200 to about 30000 but at least result 
in some data being produced -- there is none otherwise. And the picture looks 
OK!

So...looks like I will have to write a hack to convert the tuning data from 
running it under Windows (which puts it in .xls format, and somehow seems to 
manage without the frequency offsets) to a channels.conf format. Unless there 
is something obvious I am doing wrong with dvbstream -- but others on this 
list have reported similar problems, so guess I'll just go ahead.
