[mythtv-users] HDTV question for newbie

[rgoodkin at zaius1.homeunix.org]

Hello all,

You all have been very helpful here, and I guess I have a couple of 
questions.  

1.)  Is there a tuner card out there that will decode digital signals?  
Do the cable/satellite companies follow a standard for digital 
programming?  It seems the only way to do it is have the set top box 
decode the digital signals and have myth just externally control the 
tuner?

2.)  Is it possible to get HDTV broadcasts that are done over DIGITAL 
means to decode on the PC?  I guess I don't know how this setup works in 
the real world.  Does the set top box just spit out a signal that is 
equivilant to a broadcast HDTV ATSC?  What capture card do I need to get 
these resolutions?

Thanks
