[QUOTE="CyberSimian, post: 1270099, member: 141969"] At my location, the main service transmitter (Rowridge) is roughly due south, but there is another transmitter (Hannington) that is roughly due north. I am just about midway between them. My aerial points to Rowridge, but all Yagi aerials have secondary reception lobes in their polar diagrams, and one of the lobes is at 180 degrees from the direction in which the aerial is pointing. So I have a secondary reception lobe pointing at Hannington. When I tune my Humax DVR, it often picks up one of the Hannington MUXes, although it rarely picks up more than one. However, MP never picks up Hannington. The reason is that MP uses a "tuning parameters" file that defines the frequencies of the MUXes for Rowridge, so MP never tries to tune Hannington. MP [i]can[/i] perform a "blind scan", whereby it tries to receive every frequency in existence. If you do this, then you can receive signals from multiple transmitters. If you live in an area served by more than one transmitter, you may [i]want[/i] to receive signals from more than one transmitter (e.g. to receive local content that differs between the transmitters). To receive only the MUXes that you want, you should modify the tuning parameters file so that it specifies the wanted MUXes, and excludes the unwanted MUXes. The wanted MUXes might be all from a single transmitter, or might be a combination of MUXes from two or more different transmitters. Would a "Pick strongest" setting be useful for "TV Server"? Yes, extra options are always useful in specific situations, but I don't think that it would be widely used. -- from CyberSimian in the UK [/QUOTE]
