That is what I use it for, as well

Probably should be added.

Those patches are still pending.  They would require someone like
Daniel or Janne to review them, and both of them have had more
important things to work on.  There is even a chance that they will
never be committed.

Feel free to add to the wiki.

The problem is highly dependent on the STB.  That being said, I
believe most STBs would require that sleep for reliable operation with
0.22.  Since 0.22 requires an *external* channel change script for the
HD-PVR, it is up to the user to include it.

When the HD-PVR's irblaster works more reliably (in linux), internal
support for it may be added to Myth.  If that happens, it will be an
interesting to see how this problem is handled.

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