[mythtv-users] Video output size changed

[Jim]

I rebooted my BE/FE Saturday and when it came back up the picture was no 
longer full screen. It's not quite letterboxed, it's somewhere between 
full screen and letterboxed. It's got about a 2" black band across the 
top and bottom and about a 1" band down both sides. It's connected via 
HDMI to a 44" Samsung, as it has been for a couple of years.
I don't think it's a myth issue as the toolbar on the desktop is the 
same way. It stops about an inch from the screen edges. It seems to not 
know the tv/screen size anymore.
Ignoring the fact that it is not using the full screen the aspect ratio 
is wrong, things are now squished top to bottom.

I don't understand what could have changed. This has been working fine 
since I updated to v29 on Jan 1st. And on v0.28 for several months 
before that. I have not made any changes. I did try rebooting several 
times and now it is always coming back up like this.

Here is version info fixes/29 [v29.0-71-g339b08e]

There is a lot about waiting for video buffers and VDPAU errors.

and here is a backend log

This log shows some errors about not being able to find channel 4_1. I 
know that issue and I'll fix that.

This pc has an NVIDIA card in it and I'm wondering if the driver has 
gotten corrupted. Not sure what to do about that.

Any suggestions?
