Depends on the AMD64 processor. I have a dual core AMD64
4200+ and it has no problem at all with HD decoding.
The extra recording overhead isn't an issue with one
additional HD stream. Recording uses very little CPU
with ATSC/DVB broadcasts because they are already
encoded when transmitted. They do use extra disk
bandwidth, but until you get to three streams this is
usually not an issue. Even with three streams you should
be able to handle it with a JFS or XFS filesystem.
A 2.8Ghz HT P4 can handle 1080i decoding without resorting
to XvMC, a similarly classed AMD 64 chip should be able to
handle it as well.
