I added this now for testing and got lots of debug messages. So, the
patch works and the debug messages work in principle.
Also, I printed out the actual poll time according to MythTimer and it
So, if I understand the code correctly, the first poll should be with a
10ms timeout and the 2nd try with 2500ms.
I think this is another proof that poll() does not care about the
timeout, because otherwise I should get a retry every time.

I don't exclude that my SAT equipment may have a problem every now and
then, because it happens mostly on 1 or 2 multiplexes, but I think that
MythTV should better handle this and it seems the code is written with
that in mind. It's just that it does not work, because it does not retry.
