[mythtv-users] Tuning problems

Hi all,

I've had tuning issues for months now, but we mainly watch downloaded 
content, so I've not worried too much about it.

However, there's not much point using MythTv without the TV bit! :-) And 
I know how great it can be when it's working, so I'd like to sort this 
out if I can.

Here's the issue ...

To keep things simple, I've got 2 SD tuner sticks installed at the 
moment. I've got a HD one waiting to be used too, but I'm not too 
worried about HD TV. I'd rather just get the 2 SD sticks working again.

I'm in the UK and should be (at least we used to be!) in the Mendip area.

Here are the details hoe how Mendip 'should' tune ...

The settings are different to what they were a few years ago, but to me 
it looks like I the main channels are at 562000000Hz, 578000000Hz.

When I do a full scan, with MythTV, it gives me transports like ...
698000000 Hz,
738000000 Hz
690000000 Hz
721833330 Hz

Auto turn always results in finding channels, but they are temperamental 
and unreliable.

This wouldn't be a problem as MythTV always seemed to tune to the wrong 
transports. The problem is that if I edit the transports, like I have in 
the past, to mathc up frequencies, then the system fins nothing!

Back when things used to work, manually editing the transports would 
solve everything and I'd have rock solid tuning. however, that's not 
been the case for along time now.

Any ideas how to get to the bottom of this?

I should mention that if I need to go to the command line, my level is 
'ls' and 'top'! :-) I can follow instructions, but have no idea what I'm 
doing in there.

One final thing to mention is a new error message that I'm noticing when 
I go into the Multiplex editor. It's stated saying:
"Sorry, the Transport Editor can only be used to edit transports which 
are connected to a card input."

However, it then seems to work fine.

Hope some of you geniuses can help! :-)
