When a channel is mapped to a tuner it tells TV Server "you can use that tuner to tune that channel". Without mappings, TV Server won't use a tuner at all.To create a mapping, select the target tuner up the top, select the channels that you want to map/link on the left, and then click ">>". That's all there is to it.Unmapping (the opposite of mapping - telling TV Server it can't use a tuner to receive a channel) is similar: select tuner up the top, select the channels that you want to unmap/unlink on the right, and then click "<<".From your previous log files (thanks for those <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /> ) it looks like TV Server is changing channels in around 1 second. I'm not sure whether that is what you're seeing or if you consider that slow. A little more info would be helpful.One tip I can give you up front is to consider tweaking the zap timeout setting:<a href="http://wiki.team-mediaportal.com/1_MEDIAPORTAL_1/141_Configuration/MediaPortal_Configuration/13_GUI/6_On-Screen_Display_*" target="_blank">http://wiki.team-mediaportal.com/1_MEDIAPORTAL_1/141_Configuration/MediaPortal_Configuration/13_GUI/6_On-Screen_Display_*</a>Five seconds (default) can be a bit slow for some people.They look okay to me. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />The tricky thing with signal strength/quality readings in general is that different tuners use different reporting standards.I should say first that MediaPortal expects a 0-to-100% value.Most tuners give us what we expect; some seem to follow the Microsoft BDA specification which has a technical description of what the values should be; others do their own thing.When I wrote the CableCARD tuner code I wasn't really sure what value ranges we'd see, so I decided for a start that we should use raw values rather than trying to translate them into the 0..100 range.Unfortunately I didn't realise that a good signal strength reading should be round about 0 [dB]. To be clear, when you see your signal strength value is 0 that is actually a good thing.The signal quality comes from the signal-to-noise ratio. Thirty-something has turned out to be a reasonable value.In short: your signal strength/quality is absolutely fine. It is just the fact that it is shown on a 0..100 scale that makes it look bad.mm</blockquote>
