Part of the HDMI spec, is copy protection all the way through to the
display device.  While not all STBs turn that copy protection on, most
do, and they probably all will before long.  The only sure way of
being able to record is to keep it in the analog domain which does not
have copy protection.  That is why Hauppauge went with a component
capture device instead of HDMI.

Turning 1920x1080i or 1280x720p analog video into H.264 takes quite a
bit of muscle.  That is why the Hauppauge HD-PVRs are external
devices, and why they are as expensive as they are.  If you really
think about it, the HD-PVR is actually fairly inexpensive for what it
does compared to a ATSC/QAM capture device.

BTW, the HD-PVR uses a 5v/3a wall-wart.

Personally, I use a HDHomeRun hooked up to an antenna to get all the
OTA stations.  I only use the HD-PVR hooked up to the STB for the
non-OTA stations.  The vast majority of my recording is via OTA, and I
really could probably get by with just one STB/HD-PVR combo, but I
decided it was worth the extra $ to have a second one.

Q: Why is top-posting such a bad thing?
