[mythtv-users] 1 PVR-250 for Digital and Anolog Cable

[Jim Valavanis]

OK, I thought I can do this but I'm stumped.  I currently subscribe to 
Digital comcast cable.  I have mythtv recording standard cable only via 
the coax-connector directly into the Hauppauge PVR-250 tuner.  This 
works fine. 
So, I wanted to use the S-Video (or component) on the *same* 250 card to 
record the digital or higher channels too.   What I've done thus far..

1. In mythtv-setup I added another Capture Card (even though I only have 
1) to add component4 output.  The tuner0 is already setup.
2. Then in Input connections, I enable component4 to use the same 
comcast digital cable channels, as the tuner0.
3. Restarted mythtv-backend.

Now when I go to watch Live TV I am able to hit the "C" key and switch 
between tuners (component4 and tuner0) and this worked OK for Video 
only.  The tuner0 input still works fine for both audio and video.
I have the component4 (digital video output from cable) receiving the 
video signal fine.  I have to manually tune the cable box for now.  I'm 
planning on setting up the IR blaster for this.  The sound is not 
working obviously due to no audio input connection to the PVR250.  Coax 
carries both video and audio, but...
How do I enable the audio for the digital cable?  Currently the digital 
cable box, has only 2 audio Left/Right outputs that are already going to 
the TV's audio in.  There is no other available audio out on the cable 
box.  Do I use a splitter for this?  Also should I plug the audio into 
the PVR250's "line in"?

Next, if this does work with only 1 PVR250, can I somehow configure the 
recordings to use the proper input?  component4 for the digital cable, 
and tuner0 for the analog?

FYI, The digital cable box is the Motorola DCT5100 that also includes HDTV.

Thanks for all the help!
