[mythtv-users] Selecting different sources

[Nathan A. Smith]

Hi,

As I continue my weeks long quest to get all the kinks out of my myth
setup, I will introduce areas I am struggling with.

For this topic:

I have straight cable going into my mythbox (via a pvr-500) and cable
coming from my digital cable box going into the same pvr-500.  My
question is: how do I switch sources?

http://www.mythtv.org/docs/mythtv-HOWTO-11.html#ss11.1

Says that Y switches between multiple cards...  But doing that only
results in seeing the same stream again (yes split out by my pvr-500 so
the channel maybe different).  

I have setup in mythtv-setup, 

/dev/video0 (Tuner) -> cable
/dev/video0 (Composite) -> cable1
/dev/video1 (Tuner) -> cable


So any help with this would be greatly appreciated.
