I have suddenly found that media centre when opening live tv i have the sound but no vision. It displays the progress bar OK and you can can even display the active thumbnail when you left click progress tracker,but just black full screen,i have all latest drivers for sound and graphics.I have reloaded direct x and codec drivers ,tried retuning ,tried resetting monitor,all to no avail.
My system OS is w7 x64 ,CPU 6600 O/C 2.4 GHz, GPU NV GTX460.4MB Ram.
Have solved problem !
Believe it or not but clean install of previous nvidia driver 280-26 and every thing OK.
I did check by changing to latest 285-62 an problem re occurs.
So hove posted a bug file with Nvidia.
THANKS FOR THOSE WHO TRIED TO HELP AND HOPE THE INFO MIGHT HELP OTHERS WHO FALL INTO THIS TRAP.
I have suffered with the same problem of nf sound but no picture and found that it was due to a recent graphic card update. If you have a Nvidea GeForce graphics card try reistalling the a previous version of the driver. I have a 560ti card and suffered with this issue when i updated to the most recent driver. i re-installed the previous one and my Media centre works fine now. Give it a go you never know.
Thanks finleym, it has taken me a lot longer than it should have to find this solution!. I should have worked it out after a re-install, but could not understand why the NVIDIA driver would only effect media center and not WINTV!
I was getting very annoyed with all the spurious 'solutions' good to find this site.
The solution is to replace Nvidia software 285.62 with either the older 280.26 or the debugged 285.79 driver. Not the first mistake in Nvidia's history. I do wish someone in Nvidia would take more care before these launches
