<div class="moz-cite-prefix"> Setting the Aspect Ratio to "0%
{32:9}" fixes the video display which is great and a bit
unexpected as the GUI is still streched out with the characters
far too big.<br>

but if I then decode the EDID HEX data that it provides, I don't

Sorry - my mistake. I thought that code had gone into 0.31/fixes but
my recollection was wrong.
Essentially there looks to be a problem with your display's EDID. Both
Qt and MythTV get your display size wrong and calculate an aspect
ratio of 1 (and there is another issue flagged that is EDID related).
As James said, does it not just work if you set the aspect ratio to
32:9? which I assume is your display's aspect ratio?
</pre>
<blockquote type="cite">
<pre class="moz-quote-pre" wrap="">However, I do expect this ratio
to be related to the mythfrontend window size rather than the display
size, which is not what other comments seemed to imply.
</pre>
</blockquote>
<pre class="moz-quote-pre" wrap="">
The code that calculates where to place your video on the screen needs
both the screen aspect ratio and the pixel aspect ratio. Most modern
displays have a pixel aspect ratio of 1 - i.e. square pixels. For
older displays, this can only be calculated from the screen dimensions
and the resolution.
In master/0.32, the new default is to assume a pixel aspect ratio of
1:1, which would in your case just work out at 32:9.
If setting the aspect ratio explicitly to 32:9 does not work, then
please post another log with that setting in use - as that would
suggest a bug.
Regards
Mark
