I know that this may be late for you lolitta73, however it may be useful for future visitors. 

Recently I have had the same behavior and the problem was that at one point (normally few seconds after starting decoding process) I was sending into the module two consecutive StartOfFrame signals without EndOfFrame signalling in between. And now you can use SignalTap in order to scope the problem! ;)
