I have some changes in the code that makes locking faster on Twinhan, couple 
of other modifications are also there, along with CA.
I will post out once things are settled down a bit. 

Regarding the Terrestrial cards with Twinhan they have the Philips tuners 
rather than LG on the newer cards. I'm talking about the VP-3040 card, that 
comes with an addon CA daughterboard. Signal quality has to better on that 
compared to the VP-3020/3021.
