I'm not ruling out the possibility of a problem with the demod, but just trying to make clear that there could be other explanations, and the UNC counter is not the only indicator that there could be a problem. For example, the demod and tuner could be working fine, but if further down the pipeline the cx18 driver drops half the packets then the UNC would be perfect but you obviously couldn't expect the video to play back properly. Also, the different applications vary drastically in terms of how they well they compensate for errors. You could have a well written MPEG codec which handles a high threshold of errors without you noticing, and you could have worse codecs that reset the stream on even the slightest of errors, which would be highly noticeable.
