I rewrote them from scratch.

No need to check the value here. later I check against the supported 
values of the tuner device.
Also changed to direct cast: i_standard = var_GetInteger .....
I keep var_Create because the code looks more consistent. The whole 
module has to be rewritten anyway some day...
There are other issues, but I prefer to keep it homogeneous.

I fixed the leaks of p_TV and p_KS.
