[linux-dvb] Re: dvbtune problem on Redhat 8.0/Mandrake 9.0

[jhall@UU.NET (Jeremy Hall)]

hmmmm!

I remember seeing these wierdos too, only if using -i, not -x.  I also
remember modifying the dvbtune source in my local copy to figure it
out.  Unfortunately, I don't remember now what I did to clean this
up.  I'll look through some diffs and see if I can figure it out.

ah yes, I now remember some of it.

It all depends on how fast it can spin through recursion.  When it outputs
info but no stream info, that means it is tuned to a transponder other
than the SDT entries it is looking at.  This happens on Dish Network when
you're not tuned to TP 2 because they transmit the NIT and SDT entries for
TP 2 on network 4100 in the "this network" or "my network" (not "the
other" network)

I ended up making a mess of my source, so I'll need to start over, but I
think I can come up with something that will work.

I do not get viruses because I do not use MS software.
If you use Outlook then please do not put my email address in your
address-book so that WHEN you get a virus it won't use my address in the
From field.
