You should perform a channel scan in "TV Server Config" if you have not done this within the last few days. Remember to select the Enable channel movement detection setting.Modern TVs automatically rescan when changes occur, but MP's "TV Server" does not.(2) If your HTPC receives its signal from the same aerial as your TV, unplug and replug all of the co-axial cables. Sometimes oxidation can build up on the plugs, reducing the signal. Unplugging and replugging should clear some/most of the oxidation.(3) Check cable routing, and ensure that the co-axial cable does not run close to and parallel to an HDMI cable. A poorly-made HDMI cable can radiate signals that can interfere with the TV signals (but not at all frequencies). If the cables must cross, try to ensure that they cross at 90 degrees. Also, perhaps try a different HDMI cable, or a different co-axial cable.(4) If your HTPC receives the signal from a separate aerial, try swapping the aerial connections between the HTPC and TV (so that the HTPC receives the signal from the TV's aerial).(5) If the Talking Pictures MUX has moved to a higher frequency, it is possible that your aerial is no longer suitable. Aerials have physical dimensions that are optimised for a particular range of frequencies, classified by letters: group A, group B, group C, group D, and the now defunct group E. There is also a wideband group called group W. Group A aerials are optimised for lower frequencies, and will have poor response at higher freuencies. 618MHz is on the high side. I use a group A aerial, but my highest frequency is 530MHz. If the Talking Pictures MUX has moved to a higher frequency, you may now have a mismatch between the aerial group and the frequencies you are trying to receive.There is no simple way of checking this. It probably requires employing an aerial installer to replace your existing aerial (cost: perhaps £250?). So you don't want to do this unless you have exhausted all other possibilities.(6) Tuners in HTPCs are less sensitive than tuners in TVs, so your HTPC may simply be too insensitive to receive a weak signal at adequate quality, whereas your TV has no problem with it. If this is the case, you will either need a better aerial, or accept that you cannot watch or record Talking Pictures on the HTPC. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite3" alt=":(" title="Frown    :(" loading="lazy" data-shortname=":(" />-- from CyberSimian in the UK</blockquote>
