With a little bit of work, I did get it installed. But unfortunately
it still locks up after just a few recordings.

Building (Solved)
----------------------------------
1) Hit the same build problem again.  Luckily I found s a message
Jared posted on Monday with the workaround.
http://sourceforge.net/mailarchive/message.php?msg_id=27353778

2) Rebooted

$ dmesg | grep lirc
[   13.993572] lirc_dev: IR Remote Control driver registered, major 249
[   13.994707] lirc_zilog: module is from the staging directory, the
quality is unknown, you have been warned.
[   13.995144] lirc_zilog: disagrees about version of symbol
lirc_register_driver
[   13.995147] lirc_zilog: Unknown symbol lirc_register_driver (err -22)

After some digging figured out that LIRC_ZILOG was no longer in the
default v4l/.config file.  So I went an added the line below rebuild,
and reinstalled

CONFIG_LIRC_ZILOG=m

3) After the reboot, things look better.

Running (Still an issue)
-----------------------------------
Light testing seemed good, but the hd-pvr stil locked up after a few
channel changes with back-to-back recoding scheduled. Infact, it looks
like it was throwing errors much of the the time, I just didn't
notice.
