I have done SD with a PCI video card and it works fine. I assume the
previous post was referring to HD not working with PCI without VDPAU, but
you will be fine with SD. However, I do agree it is much smarter and
probably even cheaper to get a mATX board with PCI-E. Since they are the
most popular type right now there are plenty of cards for cheap. You would
also be much safer going with NVidia. They are better supported and have
better drivers right now. You would be able to do HD when you want to in the
future. There are PCI-E NVidia cards that would be HD capable for $20-40
range.
