Is that a typo for the expand setting ? 760 is too wide for the 350 to handle in hardware alone. That could explain the high CPU usage. > Related to this issue I have 2 questions: > - Will it be possible to 'fix' this so that mplayer -vo xv -fs will display > the full picture on the TV and still use only a few percent CPU usage?

The video size is limited to the size of the X screen. Depending on how it's done, when the xdriver is changed to allow sizing & positioning to reduce the overscan of X itself, the maximum size of the video will be reduced as well. -- Ian _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
