A 4 megabit video of 1280*720 resolution in H.264/CABAC can barely be played on a 2.66 GHz Pentium. With CABAC encoding CPU usage is approx. proportional to the bitrate. And it's important that peak data rate during hard hi-motion scenes does not exceed a certain number since you don't want interruptions during playback.
The same stream if repacked into AVI won't require a faster processor. ;)
Most commercial videos – thank god – are progressive (and they should be) so deinterlacer should be off. If you have any H264 interlaced video, compare which filter looks best for you.
