Unfortunately, Myth does not have control over which of the HD-PVR
connections is used.  I do not know what the HD-PVR would do if it saw
a signal on both the component and s-video inputs, but I would guess
it would use the component in preference to the s-video.

The HD-PVR will record at whatever resolution it sees on the input
(even the component).  So, if the STB auto-switches it's outputs based
on channel resolution, it is just a matter of telling Myth what
bitrate to use for that resolution.

On the other hand, if the STB always outputs a fixed resolution (say
1080i), even for Standard def material, then the HD-PVR would produce
that resolution even for standard def.

On my STB, I have it configured to output 480p for 480i, 720p for 720p
and 1080i for 1080i.  I don't know what other STBs allow you to there.

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