// Exported function that takes care of setting MacroVision level
// Prototype:
//		int __stdcall SetMacroVisionLevel( int nFormat, unsigned long ulLevel );
// Parameters:
//		nFormat		- TRUE (=1) stands for NTSC, FALSE (=0) - for PAL
//		ulLevel		- MacroVision level to set
// Return vale:
//		TRUE (=1)	- success
//		FALSE (=0)	- hardware failure

// Functions are exported by WDM for using by stub. Provide service for
// programming video decoder using I2C protocol (set/get register)
// Prototype:
//		int __stdcall SetI2CRegister( unsigned int uID, unsigned int uIndex, unsigned int uData );
// Parameters:
//		uID			- external chip ID
//		uIndex		- external chip register index
//		uData		- data to be programmed
// Return value:
//		TRUE (=1)	- success
//		FALSE (=0)	- hardware failure

// Parameters:
//		uID			- external chip ID
//		uIndex		- external chip register index
// Return value:
//		[value]		- value that currently stored in specified encoder register
