This is in no way a flame about your post. It just took me awhile to
figure out why that sentence on the HDPVR wiki page isn't enough. The
statement is self evident: if you don't plug in all the cables, you
aren't going to get a recording. Duh.
The problem is that the HDPVR isn't behaving as desired or expected
when the audio cable is missing or broken. What is expected is that at
a minimum you'll get a recording with no sound. Perhaps an error could
be kicked back to the driver letting the application know something is
wrong. What is *not* expected is for the HDPVR to lock up and for Myth
to behave as if your new hardware has gone south in some way.
Locking-up in response to missing audio input is aberrant behavior and
should be addressed in the wiki.
