[mythtv-users] Non-OTA ATSC HD Capture

[Angus Davis]

I tried sending a message to the list earlier but I don't believe it 
went through, so I will try one more time. 

I want to use MythTV to capture and distribute HD content from DBS 
networks such as Voom,  DirecTV, Digital CATV and other HD sources.  To 
my knowledge, there is not any hardware available to essentially take a 
DVI input or something of that sort to preserve a totally digital signal 
path.  Note I am not worried here about capturing over-the-air ATSC HDTV 
signals.  I know there are good tuner cards out there that do this 
(however, I am not clear on whether any of the tuner cards support the 
new Zenith 5th generation ATSC chipset, which significantly improves 
reception issues -- anyone knowledgeable on this?)

The only option I know about right now would be to take DVI out, put it 
into an SDI converter (expensive) and buy an SDI-based MPEG capture card 
(expensive) and pray I don't run into compatibility problems (unlikely).

Does anyone know of a better solution for pure-digital capture of HD 
signals?  For that matter, is anyone distributing an HD signal using 
MythTV that *isn't* coming off an OTA ATSC tuner card?
