Previewing/Playing HD SHQ MP4 video in Timeline is choppy and static.

Previewing and playing back my HD SHQ MP4 video from my Sony Xacti HD video camera in the Timeline is choppy. I have to export to QT in order for me to see the video smoothly.

I have crammed the Power Mac full of RAM (8GB) and have four external FW800 drives, and have set all the system settings to playback at full quality, but it still is choppy. Is there anything I can do? Or is this HD video just too much for even this machine?

Thanks for any help.

Mac Pro Quad Core 2.8 GHz 8 GB, Mac OS X (10.5.6), 2 internal 1TB Sata Drives, 4 ext FW800 Drives

It doesn't matter how fast your hardware configuration is.

mp4/h.264 is not an editing codec, but a delivery codec.

Look at your easy set ups. There are none for mp4/h.264.

Both formats are computational intensive and to decode them for editing is nearly impossible.

convert to DVCProHD or pro res or AIC. Those are editing formats.

Thanks, that helps. I am still trying to figure out all these different codecs. I will use DVCProHD.
