Legacy hardware is an issue, but I wonder how many people are still
using it? My headaches with XvMC led me to suck it up and buy better
CPU's, then when VDPAU arrived, to buy hardware that supported that.

Since then, I've recently purchased 3 ION systems, two for my house
and one for my parents. All three cost me $200(US$ in the US) each and
all three play back my HDPVR 1080i content with Temporal 2x perfectly.
I've noticed the price on the Atom330 based ION's have dropped
considerably since the ION2 platform was released. Actually, the one
my parents got was a single core, for $218US (taxes), the two I got
later, for my house, are dual core (330) and came in slightly under
$200US. Of course, you have to add your own remote control device, but
I figure as an upgrade path those are already being used, and can be
had for under $20US as well

Hopefully VA-API will be supported soon in some fashion and this will
allow the intel graphics hardware to accelerate playback, especially
on laptops that have it and no ability to support the CrystalHD
miniPCI devices.
