[QUOTE="doveman, post: 828369, member: 67412"] OK, thanks for explaining. I didn't realise the audio/video was carried in separate packets received at different times. I guess it's possible when the audio drops-out, that the bad signal was actually less than one second but it causes the audio renderer/audio device to lose signal and reset, making the drop-out more obvious. How do you determine whether it's bad signal or one of the other possible causes though, without spending loads on replacing (possibly unnecessarily) the aerial? I've just switched from LAV to MS DTV audio decoder and had a very obvious audio problem at around 20:21. I didn't see if it affected the picture as I was at my PC at the time. I notice that TsWriter shows Continuity errors at 20:20:56 - 20:20:57 and evr.log shows Dropping samples at the same time, whilst TsReader shows Continuity errors at 20:20:59 - 20:21:00, which I don't understand as I would have thought any display problems reflected in evr.log would be in sync with TsReader, not TsWriter. You'll also notice I'm still getting the "PMT Pid wasn't found on the PAT" errors, despite doing a re-scan (on both tuners) and setting the debugoption. [/QUOTE]
