[QUOTE="mm1352000, post: 1206610, member: 82144"] You're welcome. :) Ability to continue or recover in the face of poor signal is very much dependent on exactly what part of the stream is corrupted. Some parts of the stream are more crucial than others. The longer the poor signal conditions persist, the more likely it is for unrecoverable corruption to affect the important parts of the stream. Ahhh, interesting. You're right - that doesn't really fit a signal problem diagnosis. The [I]absolute [/I]signal strength and quality values (eg. 95, 84) exposed by tuner cards are somewhat meaningless for various reasons. Their only real use is when it comes to comparison and/or trends. For example: [LIST] [*]If the numbers for channel A are lower than the numbers for channel B [I]on the same tuner[/I] then you'll know that channel B has better signal than channel A. [*]If the numbers for channel A are lower at 7PM than they are at 8PM then you'll know that you had better signal at 8PM. [*]etc. [/LIST] So, coming back to your comment: I would say that your screenshots aren't good evidence of decent signal. The primary reason I discounted both of these possibilities is that you've said the problem only affects the BBC HD channels. If it were an HDD loading or driver issue I'd have expected the problem to affect all channels and/or all DVB-S2 channels. ...but to answer your question about exclusion of processes: yes, I'd usually recommend exclusion of MediaPortal.exe, TvService.exe and SetupTv.exe. I don't think it'll help solve this particular problem, but I've been wrong many times before. :) Bingo dingo! :) That signal quality drop out is exactly the sort of evidence I was hoping you'd see. In my opinion that's a clear indication that the problem is signal related. I wouldn't expect high HDD load to affect the tuner's reported signal quality. The obvious question would be: what caused the quality drop out? That's a question I can't answer with any certainty. There are many possible causes including: [LIST] [*]a loose cable connection [*]bad weather and/or marginal dish/LNB alignment [*]local interference (eg. microwave or DECT cordless phone operation) [*]another program (eg. WMC) commandeering (or attempting to commandeer) the tuner [/LIST] [/QUOTE]
