Adair, 

I note that you are in Brazil.

What's the usual practice with Quad and migration to digital?

>> Just FYI PAL-M subcarrier is not 4.42 MHz. The 4FSc is 909 times H rather than 910H for NTSC so the subcarrier is a little lower than 3.58. That said, I don't know how you'd play it back and convert it to NTSC.
