<font size=3>While I never assumed that I could have the WinTV PVR 150
encode two video streams simultaneously, I did assume that I could have
it switch from one input to the other depending on the channels supported
in the respective video source and the requests being made by the
recording software or live TV viewing. <br><br>
Since my first video source supports analog channels 2-82 and is attached
to the tuner and the other video source supports the digital channels
above 100, I thought myth could distinguish between the two video
sources and schedule their use to occur non-simultaneously. <br><br>
What I hear you saying is that myth will only support one video source
per encoder even though mythtv-setup allows you to configure multiple
video sources on the card. <br><br>
if this is true, I am puzzled by the following statements in the mythtv
docs
(<a href="http://www.mythtv.org/docs/mythtv-HOWTO-9.html#ss9.1" eudora="autourl">
http://www.mythtv.org/docs/mythtv-HOWTO-9.html#ss9.1</a>) see
bolded.<br><br>
<i>Input Connections<br><br>
The final configuration item is Input Connections. On this screen, you
will associate the various video sources you defined earlier with a
physical input to a encoder card. It's entirely possible that you have
multiple tuners, and each tuner has a different input, so on this screen
you let MythTV know which device will connect to which input
source.<br><br>
When you start this screen, you should see a listing of the various input
connections available on each of the Capture cards you defined earlier.
<b>For example, you may have a capture card with a tuner, a SVideo and a
Composite connection. </b>If you wanted to associate the tuner (a.k.a.,
"Television") with an "Antenna" source you defined in
Video Sources, you would move to the /dev/videodevice (Television) ->
line and press the space bar. Using the left and right arrow keys will
show you the various choices you have already created for video source.
In our case, you would use the left/right cursor keys until
"Antenna" was shown in the Video Source field. Press down to
move to the next setting.<br><br>
<b>NOTE</b>: <b>Don't add a video source to a hardware input if you don't
actually have anything connected there. For example, adding
"Cable" to the Tuner and to the Composite inputs without having
something connected to Composite will lead to blank recordings</i>.
<br><br>
</b>The two bolded sections seem to suggest that you can have multiple
inputs to a single encoder card as long as they each represent a distinct
physical video feed. <br><br>
I am confused...<br><br>

You only have three tuners. 2 on the 500, one on the 150. <br><br>
Yes, they have multiple connectors. Yes, technically the composite
video<br>
input isn't a tuner connection. It's an encoder. No, that card
can't<br>
encode from both the coax and composite connectors at once.<br><br>
And Myth currently doesn't have a good concept that two program<br>
sources are available from one tuner device, but that only one<br>
of them can be active at a time.<br><br>

The first of these cases is correct.<br><br>
Now, your cable box is presumably a superset of the clear analog<br>
cable channels, so just configure that. That gives you the<br>
maximum availability with the hardware you have.<br><br>
You can replace your 150 with another 500, and put one of the<br>
tuners there on the cable box and the other on the raw cable<br>
feed. That will work, too.<br><br>
