260.19.21 & Dell XPS M1330: no smooth playback on 1080p
I tried version 260.19.21 on a Dell XPS M1330 laptop (GeForce 8400M GS). On 1280x800 my 1080p files play fine, but if I connect the laptop through HDMI to my TV with 1920x1080, then it seems to loose every other frame. The movie looks like an old animated cartoon.
Moving to 16 bit display depth did not help. I also tried disabling the internal TFT, but without luck.
Can anybody reproduce this? Did I miss some option to increase memory size for the card?
Any helpful comment would be highly appreciated.
