I've a Dell XPS m1530 Laptop with a GeForce 8400M GS running Windows Vista Home edition that I use to watch films on my TV. It works fine but the Media Classic Player has always played HD content very badly. So badly that I normally play it in Windows Media Player 11, which works fine.

Could any one suggest why this is and how I could fix it? I've the latest Klite Mega Codec pack installed and this seems to make no difference.

I'm assuming each player is using a different codec so I think I'd like to know how to make the MPC use the h264 codec that the WMP is using. But I'm not an expert.

Any help appreciated
