[SOLVED] Video tearing in XBMC Eden

I am on Win 7, 64 Bit, XBMC Eden, No graphics card / hardware acceleration.

Here is the log file. http://xbmclogs.com/show.php?id=6182

I noticed starting yesterday that ALL movies exhibit tearing... sometimes a LOT of tearing. I believe there was a windows update in the last week or so and this appears to be related but I cant find out what exactly. The movies are actually unwatchable now..

I have attached the log files, starting with line number 1683 onwards (dark knight).

Any pointers are appreciated.

Edit : Solved. Please look at my response in this thread.

I only use external players, but I seem to remember that using true fullscreen instead of a fullscreen window always cured my problems with tearing.

I checked and I am using true full screen. Thanks for the pointer.

Enable AERO

And if that doesn't work toggle through your VSync options in the XBMC settings.

The vsync is on.

Curious why should enabling Aero matter ? I will test it later in the evening.

Because AERO isn't just eye candy, it's a strong vertical sync. Why was off? Performance? Similarity to XP?

Late update. - Aero was / is Enabled. Still notice tearing. Miraculously a bit better, but still there.
Weird thing is.. little / no tearing when the camera pans top to bottom. Noticeable tearing when the camera pans left to right.

Any pointers?

In the VGA driver settings. there is an option to override vsync. check if it's not disabled.

Enable "Use fullscreen window rather than true fullscreen" in XBMC system/system/vdeo output will often (not always though) result in tearing. Disable it usually fix tearing issue.

Do you have AVR in between HTPC and HDTV? If you do, you need to set AVR to pass-through video......
