Hi,<br><br>I have a 2.8GHz 1GB RAM, Fedora Core 5 combined frontend/backend, with 3 DVB-T tuners in the UK. I'm now trying to transcode some of my recordings to MPEG-4. I've gone into mythtv-setup and checked jobs is set to low priority. I have a dual screen setup (from an NVidia card), using XVMC on the TV-Out. I have KDE running on the monitor so I can do work on the computer whilst watching TV. The problem is when a transcode job starts, the other applications become sluggish. If I look at "top", I can see mythtranscode is using about 95% of the CPU! This sounds similar to this post:

<br><br>Has anybody got any other ideas? Can anyone tell me if its safe to try pci=noacpi?<br><br>Thanks,<br><br>Jonny<br>
