Something similar happened to me a couple weeks ago. I'm running
0.24.1-fixes with an NVidia G210 card and an Intel i3-540 CPU. One day
audio and video were fine, the next day I had audio but video was
black. I'd made no software or hardware updates in between. The logs
didn't appear to offer any clues. I tried connecting via both HDMI and
VGA, but it made no difference. In my case I had been having other
problems in the box (random shutdowns), so I thought the culprit was
failing hardware.

Unlike you, switching to the Normal profile worked for me. I was also
able to get video by creating a new profile that used the Standard
decoder with the vdpau renderer. I'm curious whether that will make
any difference for you.

I too welcome additional troubleshooting ideas for this issue.
