I do have these cables, I could give this a try if this would be  
useful....

Is this driver designed to work via a simple cat redirection like the  
pvr250 port does? I'm wondering why you are focussed on the Myth port  
as opposed to capturing video this way?


For starters, here is the mythbackend output to stdout when I start  
it up:

Like I said before, the error message I get from trying to watch TV:

> 2007-02-27 16:56:48.636 MPEGRec(/dev/cxm0) Error: error reading
> from: /dev/cxm0
>                          eno: Device not configured (6)


Which is the same as:

> # cat /dev/cxm0 > test.mpg
> cat: /dev/cxm0: Device not configured


Is this information useful?
