Thanks very, very much Dave,
I added the transport stream as per your suggestion and also replaced
my ariel cable as mine had a gender changer on it which may have been
preventing a strong signal. I got Seven straight away but still
couldn't get SBS. I can't get it on normal TV though so I guess it is
no problem. I just wish I could schedule mythbusters because it is
cool on Discovery.
Also, I take back my bashing of the new scanner. While I still think
it may be wise to provide the ability to manually enter the channel
setup data as you could in 0.16, I think it is pretty cool that most
of it is done automagically for you and can be repeated easily. I
guess I just needed to understand it all a little better.
Regards,
Dave
