<pre wrap="">My setup consists of a PVR-500 with a standard analog PAL signal

in. Now the resolution on that might not be very hight. However I
output it on a HD-Ready Samsung LCD TV. This is fine, but I notice
that all OSDs I try get a really really low resolution making the
font
and graphics edgy and not looking nice at all. By judging from the
screenshot in the wiki (<a class="moz-txt-link-freetext" href="http://www.mythtv.org/wiki/images/9/93/Isthmus.jpg">http://www.mythtv.org/wiki/images/9/93/Isthmus.jpg</a>

here?

<pre wrap="">How are you getting it from the computer to the TV?
I.e. Component Video, HDMI, DVI, S-Video...?

I'm currently doing my output via VGA @ 1366x768. Everything looks
great except the OSD. I know the OSD usually is a low resolution
compared to the actual theme, but still - pictures dont lie, there has
to be something wrong with mine which is clearly visible when I look
at the wiki screens.</pre>

Sebastian, <br>
As far as I can tell, this is the way it is supposed to work. I run
mythtv into a 61" 1080p set over HDMI and I can definitly see that the
OSD is rendered in the same resolution as the video before it is scaled
by the video card. I mainly watch SD content from a pair of PVR-x50s
and there is noticeable aliasing on the OSD letters. If I playback a
sample clip of 720p or 1080i content, the OSD is rendered much better. <br>
<br>
I might be wrong, but I think the only way to render OSD better would
be to scale the video to the TV's res in software first, then apply the
OSD. This would take a LOT of CPU power, and remove the whole point of
xvideo overlay doing hardware scaling. <br>
