Particular MKV file lags?

[BlackScarlet]

Usually I can play large MKV files just fine, but 13GB Black Swan mkv lags every few seconds making it unplayable. I don't usually have problems with MKV so I don't see how it could be a codec problem, does anyone know what?

My work laptop w/ Core2 Duo P8700, can play mkv - but only 720P w/ audio at a lower bit rate. 1080P videos pose a bit of a challenge. Perhaps that's what you're experiencing? Do a search for mpc-hc & DXVA. Enabling video acceleration might help.
