<pre wrap="">problem. Also, under Settings / Appearance / Video Mode Settings, I
have "1020x1080" selected under all of: "GUI", "Video Output:", and all
"Output:" settings for "Overrides for specific video sizes". These all
seem to be working fine, but in 1080i.

Thanks, Mark. That did the trick.<br>

Mythtv does not currently differentiate between interlaced and
progressive modelines. It is presumably accepting the first 1080
modeline it receives, which happens to be 1080i. If you deselect that
option, it won't try to switch the mode in the first place.

Hmm... this is part of what was so puzzling: since this is a recent
version of the Nvidia driver, there aren't any modelines specified in
my xorg.conf file. Just a <br>
"Modes "1920x1080_60"<br>
instead. So I gather there must be some handshaking and communication
going on between the nvidia driver, xorg, and mythtv that generated the
1080i mode information.<br>
<br>
Anyways, thanks for your quick response: it now stays at 1080p. Now I
just need to dig back through all the other info for the optimization
tips <span class="moz-smiley-s1"><span> :-) </span></span>. (I see
Xorg cpu usage periodically cycling between <1% to >84% playing a
pvr-150 mpg recording...)<br>
