Right now, I have a little splitter that splits my signal between my  
PVR 250 and my TV coming out of my sat receiver... It's extremely  
basic, but it does the trick for now. Once I get Myth working, I plan  
to buy the Hauppauge MediaMVP.

I believe that while satellite systems like Bell ExpressVu and  
several others offer digital TV as an option, they simultaneously  
offer analog programming. Well, I guess it is obvious that they do,  
since I can watch TV on my old CRT =) For now, getting analog to work  
is just fine with me!

I will do so. I know that when I'm Googling list archives, they often  
seem disjoint and it is hard to follow threads. However, I'm flexible  
and so will abide by your request!

Just to cut to the chase, I progressed a great deal today (I would be  
happy to detail my experiences to you privately for your how-to).  
Where I'm at now is that Myth is all setup, but unable to view TV  
because of what appear to be driver-related issues. Specifically,  
error messages such as the following:

Doing this command as well, and:

I've enabled mythtv logging, but so far I'm not seeing anything  
there... These errors are being spewed out to stdout.

Let me know if you have any questions. I would be happy to help with  
your guide as best as I can!
