Ping!!  First, did this hep Theirry?

And I am still dead here,

I have installed all the xawtv stuff only to find that no ATSC 
functionaliy has been added. It can get the 1 signal from a 10 watt 
translator about 20 miles away that is still broadcasting in NTSC 
format, but at that distance and wattage, the signal to noise is about 
1/1 when conditions are good, perhaps 5% of the time.

I have installed all the dvb_apps and friends, but  while it finds 
the "Oren OR51132 VSB/QAM Frontend" doesnt support TERRCABLE_ATSC
apparently not finding the atsc list for std terrestrial broadcasting in 
the US, so until I can find a configurator to tell it different, thats 
out.

That leaves kaffeine, whose scanner scans about 3 or 4 channels a second, 
not giving this card adequate time to lock to the signal so it 
registers.

the KDE version of kaffeine did in fact work well with this card an 
iteration or 2 back up the log, not too long before I installed TDE in 
fact. However, I can find no means to slow its at least 10x too fast 
channel scan that it does now. And the site it got program listngs from 
seems to be defunct too.

Is there not another application yet that will play ATSC broadcasts?
