There are a whole lot of "mode is valid"s and a whole lot of "mode is invaild"s. It certainly seems like the TV EDID is being properly detected and the NVIDIA card is making the right choice. I don't remember if I mentioned that I did go through and change the resolution through the NVIDIA control panel with no change.<div><br></div><div>Using a different myth box made no difference (although that uses the same NVIDIA drivers). </div><div><br></div><div>I did change my audio output to go out the headphone jack instead of through the HDMI cable. When I did that (using the internal player), the sound came from the speakers,
but no video was displayed. That makes it seem like maybe it is a configuration problem.<br><div><br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"><div id="yiv1941640108"><div><blockquote type="cite"><div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;"><span style="font-family:'Helvetica';font-size:medium;"><b>From: </b></span><span style="font-family:'Helvetica';font-size:medium;">Andre <<a rel="nofollow" ymailto="mailto:mythtv-list@dinkum.org.uk" target="_blank" href="/mc/compose?to=mythtv-list@dinkum.org.uk">mythtv-list@dinkum.org.uk</a>><br></span></div><div style="margin-top:0px;margin-right:0px;margin-bottom:0px;margin-left:0px;"><span style="font-family:'Helvetica';font-size:medium;"><b>Date: </b></span><span style="font-family:'Helvetica';font-size:medium;">February 6, 2011 4:27:08 AM CST<br></span></div><div

I'll admit I couldn't really follow your explanation of the problem and just wondered if you had some old tweaks in there that was confusing the situation. If your configuration was overriding
the tv's edid completely then your video card wouldn't configure hdmi audio until something overrode it, combine that with a TV that's picky and what I understood of your scenario is possible.<br><br>I certainly had some very odd interactions going on with my GT220 when hdmi audio support was added, my Onkyo amp (since scrapped) would go crazy when given 1080p50 with hdmi audio, 1080p60 with audio was fine but that's useless with European TV.<span class="yiv1941640108Apple-tab-span" style="white-space:pre;"> </span><br><br>Good luck with it, I'd start by adding verbose mode reporting to X and look at what your TV is telling you it can support, many of them lie profusely.<br><br>In your Device section in xorg.conf<br>Option "ModeDebug" "yes"<br><br>Andre<br><br><blockquote type="cite"><blockquote type="cite">From: Andre <<a rel="nofollow" ymailto="mailto:mythtv-list@dinkum.org.uk" target="_blank"
