Thanks for advice; i looked deeply into the card 8must take off the tuner's 
cover) to see, that is an LG tuner on the LifeView card. Card is marked with 
LR50, but there's at least 5 LR50 Lifeview card in the HW database :)

Can anyone tell me, thet where can i find tuner identifiers?

Thanks for help,
