any1 already get working PAL60 or NTSC4.43 on a vivo geforce card w/ SAA71xx ?

the chip supports both modes, but the driver are not configured to choose others ones.
i use nvidia wdm drivers and i tried to change stuff in registry but didn't worked (Reg0x0E, ...)
i'm looking for a software like BtTool but for saa71xx if any1 have it...

also asus digital vcr let me choose all modes but when i choose ntsc 4.43 it say : "Error Prompt : Can't decode TV signal as the video standard you have chosen....", weird...

any1 ideas would be greatly appreciated...
thanks
