 notice that the same block (this and the next on) is reapeated over and
 over, so it seems to be a systematic error, like still calling the wrong
 HasCRC() in some places. (notice the missing message from
 mpegstreamdata.cpp)

 need to investigate this some more. I have a vague recollection of reading
 something about 0 / -1 having a special meaning in some CRC cases in the
 DVB domain but don't remember where I read that at the moment.

 thats the first repeat, it goes on like this for some time while the
 backend is actively scanning the EIT on cable but it stopped ~7 hours ago
 and the rest of the night there are almost exlusively 0x0 != 0xffffffff
 messages.
