I don't think that's a HD problem. To me it sounds more as if QC is the
bottleneck. Because this movie should playback on a MacPro even uncompressed
w/o any problem. 

see this page:

uncompressed HD (1920x1080) requires 8x 10K rpm striped SCSI disks.
maybe less with SATA but not much less.

I haven't done the maths but 2000x750 is not much less bandwidth, its far beyond what
you can do with a single disk.

you can do 2 layers of HDV 1080i from a single SATA disk, but thats with more than 10:1 compression
ratio.
