  Hey guys.

# mythbackend --version

using_live using_mheg

My Tunercards are : 3x HVR4000 Hauppauge + 2x Tevii 470

But when watching LIVETV i experiencing several long long times before 
it tunes into the channel!

I''m only running DVB-S/S2 and when changing channel i see LAM comming 
up really fast - not always are the last C comming.
Mostly it takes about a minut before the channel are tuned in.

In mythTV-setup under input sources - I've chosen to use quick tunning 
(Always) - but it takes around a minute before it tuned in.
This have only be discovered after upgrading from 0.22 to 0.23!
Several times it cannot tune to the channel...... Just standing LAMc  - 
and keeps standing there???

What can caurse this and is there a solution for this tunning problem.
