hmm actually it appears to be rather difficult: in mythtv I sometimes
get the bad channels with a perfect picture whereas the good ones are
always good.
Even szap gives me unreliable results: sometimes szap won't lock and
next time I have a solid lock (I can't test the picture though as every
channel is encrypted).
But I have seen something: all the unrelaible frequencies
(11555,11635,11675MHz) are very close to the 11700MHz Universal lnb
switch frequency, whereas the good one is very far (11093MHz).
Could that be a lead to the root of the problem?
I am still testing and trying to get some useful logs.
Bye
Manu
