[QUOTE="mm1352000, post: 1206602, member: 82144"] Hi Michael Sounds and looks like a classic signal strength or quality problem. MP only shows "no signal" notifications if tuning (ie. starting to view the channel) fails due to a signal problem. There'll be no notification if signal drops out after tuning succeeds. Your description of what happens is a typical codec response to a stream with lots of corrupted or missing chunks, so it's no wonder you've seen codec references. Both the recording and live TV attempts show the same symptoms: a ton of continuity errors in the TsWriter log file. Search the forum for references to continuity errors and you'll find the top 3 causes are: [LIST] [*]signal strength or quality problems - either signal too weak/bad, [I]or too strong[/I] [*]HDD that hosts the time-shift/record folder overloaded by other programs; usually it's some kind of security software that decides to scan the time-shift or record files as they're being written [*]driver DPC latency problems [/LIST] There are other possible causes, but they're generally rare and very technical. In my opinion based on the information you've provided so far, you have signal strength/quality problems. Yes, it [I]is [/I]possible for you to have a signal problem that only affects the BBC HD channels. The technical explanation of why it's possible is time consuming, so I won't go into detail unless you specifically ask me to. My suggestion to you would be: [LIST=1] [*]Open TV Server Configuration. [*]Go to the manual control section. [*]Select your Freesat BBC One HD channel and start time-shifting. [*]Watch the "discontinuities" (which is the number of continuity errors), signal strength, and signal quality figures. [/LIST] Normally the discontinuities figure should normally stay as zero and/or not change. When your problem is occurring, you'll see the discontinuities figure increase rapidly/consistently. My prediction is: at the same time as the discontinuities figure starts to increase, there'll be some kind of change (eg. a drop) in either (or both) signal strength or signal quality. This would be one way of confirming the signal problem diagnosis. Note you can do the same test for other channels (eg. ITV HD). [/QUOTE]
