Sometimes it would work but mostly I would get the error “should have received a lock by now….” The unusual thing was that I was getting the normal 79% to 84% signal strength so nothing had changed with the antenna setup.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I tried various things to resolve including additional updates, completely removing the DVB cards and re-adding them, rerunning TV channel scans, recopying the driver files, moving the computer to another known good signal antenna source to the point that I was convinced that the tuner card had a hardware failure. This was because when I shut down the computer hosting the MythTV installation (no point in having it running when it could not record anything)<span style='color:#1F497D'>,</span> I was able to lock channels on restarting again however the problem quickly returned on further testing making me think the tuner card had failed perhaps showing symptoms when it heated up.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In the end I swapped out my Kworld PCI device for an old Fusion DVB tuner and reconfigured it to use the Zarlink MT352 DVB-T so I was back up and running again with a single tuner. I put the Kworld <span style='color:#1F497D'>tuner card </span>as a test into a Win7 PC to test and found it worked perfectly with perfect reception on all channels. So I now know that the tuner card is not faulty but MythTV version 0.24 does not support it in the way that .023 did.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Has anyone else come across this problem as you would not expect an upgrade to break a stable and working system so completely.<o:p></o:p></p><p class=MsoNormal>Is there drivers for the AF9015 built into v0.24 that over wrote the drivers I had working so well with 0.23?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='mso-fareast-language:EN-AU'>Regards<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-AU'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:16.0pt;font-family:"Brush Script MT";mso-fareast-language:EN-AU'>TonyR<o:p></o:p></span></p></div></body></html>
