Out of the Blue Film Synch Errors, Graphics Card?

Out of the Blue Synch Errors

Yesterday my PC could play 1080p .mkv films without any problems, today the same films have synch errors? I don’t think I’ve changed any settings, the only codecs etc. I install are:

ffdshow_rev1125_20070428_clsid
MatroskaSplitter

These allow me to usually play all the files I need to within Windows Media Player without any problems. Anyone know where the films would suddenly not play in Synch? (Its driving me insane!). 720p films do not have any errors, the CPU is not (according to Windows) at 100% while playing 1080p so I’m confused!

I might have updated the Graphics driver (although as Nvidia are releasing drivers every other day I’m not sure! Could this be the problem?

Doesn't sound as if it should, but worth a rollback to be check.

Have you tried them with another player (e.g. DivX) to see if the sync issue remains?

You say its not 100% but what is it, it should be really quite low. Also I think google will be your friend because Ive read that you need to use a specific version of the h264 codec (because sometimes there different/modified).

Gone back to 169.25 from 169.28 and it seems to have worked! Very strange

Thanks
