<div dir="ltr">This issue occurred before, but I had a lot of variables to eliminate, including switching from a FireWire connection to a cable box to an HD Homerun Prime.<div><br></div><div>I am running MythTV 0.27 on Mythbuntu 12.04.3 with nVidia drivers 173.14.37-0ubuntu0.0.1 and a card lspci identifies as "VGA compatible controller: NVIDIA Corporation NV37GL [Quadro PCI-E Series] (rev a2)".</div>
<div><br></div><div>The main thing that seems to trigger it is switching around between different video resolutions and formats. Sometimes it's as simple as changing channels between SD and HD, but it doesn't seem to be consistent. However, once it goes bad, I can't play any HD video or watch live HD channels, but if I restart mythfrontend, it comes back fine.</div>
<div><br></div><div>My assumption is that the blue screen is a keying color that the nVidia driver should be playing over and something has gone awry with said driver. When the system enters this state if I switch to xlib or xshm (i.e. no hardware assist) I can play the videos that weren't working before but obviously these renderers perform far worse than xv-blit (the default) and opengl seems to be too demanding for this old/cheap video card.</div>
<div><br></div><div>Any suggestions on something I could try? I was going to leave mythtfrontend running with "<span style="color:rgb(0,0,0)">--verbose all,nodatabase" but video playback is slowed so I can't really leave it that way to wait for the problem to manifest. Something specific I can enable? Something I should be grepping for?</span></div>
