Update on this.<br><br>I have now installed both DVB cards in a completely seperate computer, with the same results (after installing a clean FC4 and MythTV). Therefore it has to be either my aerial has got worse, or the BBC are not broadcasting such a strong signal anymore.
<br><br>Can anyone who has a Nova-T card please do a tzap "BBC ONE" and let me know what values they are getting for signal strength, SNR, BER and UC please? im unsure if my values are acceptable or not. The SNR seems to be in the high D000's most of the time, but occasionally it drops out.
<br><br>Another guess is that there is some kind of interference in the signal, like a spike - does anyone think a filter in the aerial connection might help? worth a try?<br><br>thanks<br><br>George<br><br><br><div><span class="gmail_quote">

running ctvdr 4.5 (see <a href="http://www.heise.de/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">www.heise.de</a> - sarge
based I think) with one DVB-t and one DVB-s card. I too have noticed more
glitches recently, particularly on the BBC mux channels. </font></span></div>

<div><span><font color="#0000ff" face="Arial" size="2">My
transmitter is also Crystal Palace. BBC1 is usually fine but 3, 4 and the
interactive channels are particularly bad. Others are reasonably OK, even
though I have a poor aerial setup.</font></span></div>
<div><span></span> </div>
<div><span><font color="#0000ff" face="Arial" size="2">Not
sure if the BBC have altered anything, but they use a technique called statmux
(I think that's the right term), which is basically an algorithmic method of
dividing up bandwidth across the channels. BBC1 however gets constant
bandwidth to ensure all the regional variations get enough
share.</font></span></div>
<div><span></span> </div>
<div><span><font color="#0000ff" face="Arial" size="2">If
BBC have fiddled with things, then this might explain why BBC1 is stable here
but not the others.</font></span></div>
<div><span></span> </div>
<div><span><font color="#0000ff" face="Arial" size="2">Have
you checked whether there's any engineering work going on? I believe the
information is linked from somewhere on the BBC site.</font></span></div>
