There have been several threads talking about this problem, including this one: <br><br><a href="http://www.gossamer-threads.com/lists/mythtv/users/255655?search_string=slow%20recording%20menu">http://www.gossamer-threads.com/lists/mythtv/users/255655?search_string=slow%20recording%20menu
</a><br><br>I too have this problem on a FC7 AMD Athlon 2500+. I use the nvidia 9746 driver. I have never used nv or anything else. I was initially using qt menu renderer but switched to OpenGL and that actually seemed to help a little. Not sure why since it seems to be the opposite of what most people expect. I also turned on "CPU friendly thumbnails" or something like that in the setup menu. Maybe that helped a little too.
<br><br>Bottom line is that this problem did not exist in my previous setup of Myth 0.18 and I think nvidia 7174 driver. It was apparently introduced somewhere in 0.19, based on threads in the discussion archive. Still happening in
0.20...<br><br>Larry<br><br><div><span class="gmail_quote">On 10/1/07, <b class="gmail_sendername">Tom Metro</b> <<a href="mailto:tmetro+mythtv-users@gmail.com">tmetro+mythtv-users@gmail.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<br><br>Confirmed, though the OpenGL setting only has a noticeable impact on the<br>upper level menus, where it fades in/out the selections in what appears<br>to be slow motion. Overall it makes the situation worse, but it doesn't

after restarting the FE (not the computer) it'd be back. I also noticed<br>that this problem was introduced with some of the updates just prior to<br>the Ubuntu Fiesty release (Feburary timeframe).<br><br><br>As others have reported, switching to the proprietary NVIDIA drivers

was normal, but then the main menu screen appeared just as a black<br>window (I run the FE windowed). Dragging the window caused a blue<br>background to flicker into view, but no menus.<br><br>I probably could have flipped some setting in the DB to fix this, but
