How about something using a USB serial adaptor, it's pretty common to use DTR to signal there is a similar example here:

You wouldn't need the AC power relay so would be even simpler, a few minutes googling comes up with many similar projects.

btw I don't have a HD-PVR but I am an Electronics Engineer.

I would be writing the script to drive it as well.  If anyone with an HD-PVR has a micrometer and can measure the barrel size and pin size, it would make the power plug selection a lot simpler.
