Under mythfrontend's setup menu->appearance, check to see if there's a<br>setting that says 'monitor aspect ratio.' It's only there if you have<br>a newer version of Xorg or have xinerama enabled. I'm betting it's
<br>currently set to 4:3. Try setting it to 16:9 (there's no 15:9) and<br>seeing if that improves it to be a slightly squished picture in myth.<br>If that does help, then I think I may be able to figure out how to get
<br>it working at 15:9.<br><br><br>Alex<br>_______________________________________________<br>mythtv-users mailing list<br><a href="mailto:mythtv-users@mythtv.org">mythtv-users@mythtv.org</a><br><a href="http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users">

Unfortunately, I don't have the 'monitor aspect ratio' setting available.<br><br>I think I've determined the source of the problem, and arrived at a suitable (although not entirely satisfactory) work-around.
<br><br>I believe (although I cannot confirm) that my TV (a Olevia by Syntax LT26HVE) is providing improper EDID information to the SiS X driver.<br><br>Regardless of what I set the screens DisplaySize to in xorg.conf, xdpyinfo reports that my screen is 40x30 mm (apparently my 26" TV is actually a iPod Nano screen :).
<br><br>I believe that MythTV looks at the screen size as reported by Xserver to determine the aspect ratio of the screen. MythTV thinks my screen is a 4:3 aspect ratio and therefore fills the whole screen. This is correct behavior on the part of MythTV.
<br><br>Having been unable to figure out a way to tell the SiS driver to ignore the EDID information (some nVidia drivers accept a 'Option "IgnoreEDID" "true" ' option in the xorg.conf), I have a couple of work arounds:
<br><br>Work around 1:<br>Tell MythTV to display the GUI and playback in separate windows. Have both windows set to 1280x768@60Hz, but indicate that the aspect ratio for TV playback is 16:9.<br>There are two problems with this work around: a) 16:9 isn't quite 15:9 b) as Myth creates the new windows my TV losses the signal and flashes it's "no signal" screen. Twice for about a quarter of a second. It's very annoying and strikes me as bad for the TV.
<br><br>Work around 2:<br>Tell MythTV to have a horizontal overscan of -8 percent, and a vertical overscan of 1 percent (to get rid of the embedded signal info at the top). This gives a picture that is very close to 4:3 (within a pixel or two).
<br><br>I'm pretty happy with Workaround #2.<br><br><br>
