I have an H20-100 and a H20-200, both of which work very well with the HD-PVR.

Channel changing via USB<->NULL modem cable<->USB works very well.
The channel changing script can turn on the STB, change the channel,
and clear the banner.

Myth will call the external channel change script just before it tells
the HD-PVR to start recording.

If you have the STB set to "native" resolution, then it can take the
Directv STB a few seconds to lock onto a new channel, when the
resolution changes.  Because of this, it is a good idea to add a
"sleep 2" to the bottom of your channel change script, to give the STB
time to settle before the HD-PVR tries to start recording.  If the
HD-PVR tries to start recording when the STB is still in "flux", the
start of the recording can be corrupt.

At this point in time, the component outputs of the Directv STBs are
fully functional up to 1080i.   You cannot get 1080p out of them,
which is okay because the HD-PVR can only go up to 1080i itself.  The
only content on directv that is available in 1080p is some of their
pay-per-view stuff.

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
