If not, try these lines, again leaving out the Section/EndSection lines if you already have those sections and rebooting afterwards...Code: Section "Monitor" Option "DPMS" EndSection Section "ServerLayout" Option "BlankTime" "0" Option "StandbyTime" "0" Option "SuspendTime" "0" Option "OffTime" "0" EndSection== transcoding, re-encoding, compressing, and archiving ==Transcoding is when you decode video compressed in one format, and re-encode it in another. Usually, it's done for 2 reasons:Removing Commercials - decompressing a compressed video, removing the parts marked to be removed (the commercials) and re-encoding the video stream, to the original or to a different video encoder using a codec.To free up hard disk space; by reducing the quality or changing the encoding of the video to a more efficient codec (or a combination of these) space can be saved.references;* http://www.mythtv.org/wiki/Transcoding** http://www.mythtv.org/wiki/Mythtranscode** http://www.mythtv.org/wiki/User_Manual:Daily_Use#Editing.2C_Transcoding.2C_Removing_Commercials** http://www.mythtv.org/wiki/Transcode_Videodiscussion on transcoding to H.264* http://www.mythtvtalk.com/transcoding-woes-mpeg4-just-not-cutting-14908/* http://blog.gorwits.me.uk/index.html%3Fp=614.html* http://ubuntuforums.org/showthread.php?t=1673463
