Help! Choppy playback (dropped frames)

[junz]

Just bought a GeForceMX2 MX400 64mb video card and I have trouble playing SOME DivX movies. It plays smoothly but some parts are choppy and dropping frames. The weird thing is I could play it just fine with my old Intel 740 card. BTW, I use Windows Media Player 6.4

These are the things I did and still failed.
1. Installed upgraded driver for my ALI motherboard (AGP,IDE)
2. Installed upgrade driver for my GeForce MX400 card
3. Reinstalled DirectX 8.1
4. Reinstalled DivX 5.02
5. Reencoded the DivX movie using Nandub
5. Moved the slider to minimum quality level under filter properties of windows media player

Anymore suggestions please. It is highly appreciated.

Thank You and More Power.

God Bless.

Make sure you graphics card is set to maximum hardware acceleration.

You should be able to find this setting in 'control panel'->display->settings->advanced->Troubleshooting.

And you might get better preformance by enabling 'yuv extended mode and overlay extended mode in the divx5.0.2 playback filter.

my graphics card is set to maximum hardware acceleration by default. tried also enabling yuv and overlay extended mode but to no avail.

If not already done, turn off as many background operations/programs as is possible...

Tried doing that. No success still. My only application working in the background is Norton 2003.

Try increasing the AGP Aperture size from within your BIOS.
