Note that the version of the Samsung NIM that B2C2 uses is custom made. The "normal" tuner is vertical mounted. The B2C2 version is horizontal mounted and there are couple of small changes related to the I2C.
Another important thing to note is that Samsung had two versions of the NIM. In one version(older) the VS (B4) had to be reset for > 1600000. In the current version, and the version that B2C2 uses, the VS bit is reset for > 1500000. I'm not sure what the LG NIM requires.
Where is that VS? Do You mean register 0xb4 in the stv0299 (according to
spec it has only 0x34 registers)?
