Tell me more about 2d vs. 3d video.  What do you do with them, how do they
work?  What brand hardware / X11 server?
 
The TV works best if it is PCI.  That's because of the special
DMA transfer feature PCI provides.  A PCI card can write directly
to the memory of another PCI card.  That's why watching TV puts
so little usage on the CPU...

Well, the BT848/878 video chips from BrookTree are certainly
also responsible for the excellent performance, but the PCI DMA
feature is certainly important in this scenario.

I can't really speak for non-PCI TV cards...

For my system, I have the following devices:
	pci video (S3 VRGE)
	pci adaptec 2940 (SCSI)
	pci WinTV

	isa Network (10mb)
	isa Sound
	isa adaptec 1540c (SCSI)
