[QUOTE="CyberSimian, post: 1285996, member: 141969"] I am not a TV expert :eek:. Most of my knowledge in this area is empirical, and not theoretical. :D Also, I don't necessarily use terms correctly, or understand what others mean when technical terms such as "sub channel" are used. :unsure: From discussions with mm in various threads several years ago, my understanding is that TV Server tunes in turn to each selected grabber channel, and receives the EPG for one rotation of the EPG carousel (or less than one rotation if the timeout is too small). If A and B are both selected as grabber channels, and A and B reside in the same MUX, grabbing from B provides the same EPG data as grabbing from A. So grabbing from both A and B is pointless and a waste of time. Nevertheless, TV Server will do this if A and B are both selected as grabber channels. I think that the scenario when this might be useful is if the "Store data only for selected channels" setting is enabled. You might want to do this if you obtain your EPG from two (or more) sources. Example: you might want to use the "Schedules Direct" internet EPG because it provides more programme detail, but it does not provide EPG data for the minor channels that you can receive. So you would use "Schedules Direct" for the major channels, and then use the DVB EPG only for the minor channels. You would select those minor channels as grabber channels, and enable "Store data only for selected channels". If you did not use this setting, the DVB EPG would grab all of the channels, and overwrite the Schedules Direct EPG that you had previously loaded. Well, that is my understanding of how it works. o_O -- from CyberSimian in the UK [/QUOTE]
