if you try to tune a channel which has a very weak signal, then this can crash the tvservice.

[21:08:54] <i-loop|home> dirk, do you think that a weak signal could crash the TVServer?
[21:09:07] <MisterD81> Yes
[21:09:50] <MisterD81> I have a very weak signal on all HD channels and TvServer crashes almost every time I try those channel
[21:10:19] <MisterD81> There is somewhere a memory leak or something similar in TsWriter
