-The lack of CPU horsepower required to decode h264
-The lack of bus bandwidth to accommodate for the decoded video stream
Also, any P4 running with an AGP card (AGP was far more prevalent in the early-mid P4 era) automatically has zero video decoding capabilities through blobs, as NVIDIA never added VDPAU support for older generation purevideo (7xxx series and lower were the latest cards to run on AGP)
The only way he could do it would be to use a newer PCI card or PCI Express card on a P4 motherboard that supported it.
-PCI however doesn't have enough bandwidth to fit DVD resolutions comfortably let alone HD so he's either using GL output (in which case his CPU usage claim is bogus) due to its low bandwidth requirements or VDPAU for the same reason.
-PCIe is more or less the same story. GL or Xv would produce the same results, with VDPAU being the only solution to grant low usage to the CPU.
I'd nominate for the "he imagined everything and really has no idea how computationally or bandwith intense video decoding can get" option.
