That is exactly what I have been doing for my testing. So far I haven't
detected any particular pattern.
There do seem to be a few problematic channels like our local channel 12
or Bravo. Those seem to fail more often but I don't have any idea why.
If I just ran the channel script again they will usually tune.
In my testing I have been just cycling between 4-5 of the most popular
channels we use from the satellite and within a few cycles one channel
It does seem like it is often many seconds before the channel actually
changes. This is well after the channel change script has completed. I
am assuming that is due to the buffering to disk before display.
