Where do you adjust this?

I've tried already in the frequency field of the dtv_multiplex table,
but there was no improvement.


Thanks for the reply.


PS:

Now that I look, I see a glaring inconsistency:

I can't imagine how this has happened, but there's no mplexid 11 in the
channel table so it's a bit weird.

update  dtv_multiplex set frequency=205625000 where mplexid=7;     


It's working now!

*hangs head in shame*.

I wish I'd spotted that sooner!

Thanks Lee.  Can you send me a wish list or something off-list?  I'd
like to thank you with material goods!
