The initial output position can be set with the module options osd_left & osd_upper. For X, the position needs to be set in its config file. Although it's trial & error, I use fbset with the -left & -upper command options to move the display around. Once it's in the correct position use 'fbset -x' to get the mode entry for X. The number given to the -left & -upper options specify the offset in pixels from the top left corner of the tv screen. The minimum margin is 1, so 'fbset -left 1 -upper 1' moves the display area to the top left corner of the tv screen. > 2) when I use xv via mythtv to playback any content recorded at a > resolution lower than the new reduced x window size it will play back > beautifully however playback of any content with a resolution wider than > the width of the X session (or presumably taller) results in a blue > screen (with the audio playing).

This sounds like a bug. Turn on some extra debug using 'ivtvctl -D 257' & check what appears when attempting xv playback. If you haven't already, try something other than MythTV. Xine or mplayer should be fine. Even if it doesn't work, with the extra debug you should at least see an 'ivtv_yuv_init' line in the log when playback was started. -- Ian _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
