Comment (by nooneimprt4nt at gmail.com):

 I can easily reproduce this as well using DVB-S.  In fact in my case, it
 is worse, in that it often takes more than 4 retries before the frontend
 is able to read data when switching channels, so I get something that
 looks like:

 ...
 }}}
 At which point I need to restart the frontend to continue.

 Changing the default number of retries to 20 in RingBuffer.h fixes that
 problem, but I still get the 'you should have a signal lock' message
 whenever it takes more than a couple retries.
